Hooke's law forms the basis for analyzing the deformation and stress response of materials, enabling the design and optimization of structures that can withstand various loads and stresses.
• Coefficient "1= ox + oy = 0x + oy = 01 + 02" is called the isotropic coefficient and don't depend on the orientation of the coordinate system. It represents the sum of the partial derivatives of a function with respect to the respective variables in a Cartesian coordinate system. The isotropic coefficient is constant and independent of the direction or orientation of the coordinate system used. It plays a crucial role in various mathematical and physical applications, such as solving partial differential equations and analyzing the behavior of isotropic materials.
• The value of the Poisson's ratio cannot be greater than 0.5. Poisson's ratio is a material property that relates the lateral strain to the axial strain when a material is subjected to an external stress. It is defined as the ratio of the transverse strain to the axial strain. Poisson's ratio ranges between -1 and 0.5 for most common materials. A value greater than 0.5 would imply that the material expands laterally when stretched, which is physically impossible. Such a high Poisson's ratio violates the principles of material behavior and contradicts the observed behavior of real materials.
• According to Hooke's law, the strain of an elastic material is proportional to the stress applied to it. Hooke's law is a fundamental principle in solid mechanics that describes the behavior of linearly elastic materials. It states that the deformation or strain experienced by a material is directly proportional to the applied stress within the elastic limit of the material. In other words, for small deformations, the strain is linearly related to the stress through a constant known as the elastic modulus or Young's modulus. This relationship allows engineers and scientists to predict and analyze the behavior of elastic materials under different loading conditions, providing a basis for designing structures and predicting their performance.
Understanding these concepts is essential in various fields, including engineering, materials science, and physics. The isotropic coefficient helps in mathematical modeling and solving problems involving multiple variables, while the limit on the Poisson's ratio ensures the validity and physical feasibility of material behavior. Hooke's law forms the basis for analyzing the deformation and stress response of materials, enabling the design and optimization of structures that can withstand various loads and stresses.

The block diagram of Sampling Process (DSP) is given below: SAMPLING PROCESSAs depicted in the above figure, the analog signal is passed through an anti-aliasing filter that eliminates the high-frequency components present in the signal.
After the filter has been applied, the signal is sampled. The time interval between two consecutive samples of the analog signal is called the sampling interval. The sample-and-hold circuit is used to store the output of the sampler. The output of the sample-and-hold circuit is then given to the ADC (Analog-to-Digital Converter) where it is converted into a binary form. The analog signal's continuous amplitude values are represented by these binary digits (bits).
The output of the ADC is in the form of binary code. The digital output is then stored in a memory or microprocessor. The digital signal is first processed by the DSP, which stands for Digital Signal Processing. It is then transformed into a form that can be displayed on a computer screen.

Write a recursive function int is_palindrome (char *str, int n) that returns 1 if str is a palindrome, that is, reads exactly the same forwards as well as backwards. If str is not a palindrome, the function should return o. Here, n is the length of str. For example, if str = "rats live on no evil star", the call is_palindrome (str, 25) should return 1. If str = "abab", the call is_palindrome (str, 4) should return o.
Palindrome: A palindrome is a word, phrase, number, or other sequence of characters that reads the same way forwards and backward, ignoring spaces, punctuation, and capitalization. Palindromes are often used in literature, poetry, and word games. Examples of palindromes include "racecar," "level," and "A man, a plan, a canal, Panama." Recursive function:
Recursion is a technique in which a function calls itself repeatedly to solve a problem. Recursive functions can be used to solve many types of problems, including those involving lists, trees, and graphs. To write a recursive function, you must first define a base case that stops the recursion, and then define a recursive case that calls the function again with a modified input. Here's a recursive function that determines whether a string is a palindrome: int is_ palindrome (char *str, int n) { if (n <= 1) { return 1; } else if (str[0] != str[n-1]) { return 0; } else { return is_ palindrome (str+1, n-2); } }
The function takes a string str and its length n as input and returns 1 if the string is a palindrome and 0 if it is not. The base case is when n <= 1, which means the string has length 0 or 1 and is therefore a palindrome. If the first and last characters of the string do not match, the function returns 0 because the string is not a palindrome. If the first and last characters match, the function calls itself recursively with the substring that excludes the first and last characters. This continues until the base case is reached, at which point the function returns 1 because the string is a palindrome.

The given convolution of x(t) - 10e-10tu(t) with h(t) - u(63) using the convolution integral y(t) = x(t) * h(t-td τ) is given as: y(t) = - Co y(t) u(t-3) [y(t) - 151/104e^(-2(t-3)) u(t-2)] + [y(t) - 101/3 u(t-3)] u(t-1) + [1e^10(t-3) u(t-3)] - [(1-e^-10(-3) u(t)] Where, u(t) is the unit step function tD = 63

The given expression is explained below:
The components of the expression can be explained as:
N: It represents the index or time step of the signal. The signal is defined for 0 ≤ N ≤ Fs, where Fs is the sampling frequency of 33600 samples per second.
χ: It is a variable defined as χ = 1200π/Fs. This variable is used in the definition of the signal.
Γ: It is another variable defined as Γ = Π/Fs, where Π represents the mathematical constant pi (approximately 3.14159). This variable is also used in the signal definition.
Now, let's look at the signal expression itself:
K~2(N) = Sin(Nχ) - 10sin(9Nχ), 0, 0 ≤ N ≤ Fs
This expression consists of two terms:
The first term is Sin(Nχ), which represents a sine wave with a frequency determined by the value of N and the variable χ.
The second term is -10sin(9Nχ), which represents another sine wave with a frequency 9 times higher than the frequency of the first term. The amplitude of this term is -10 times the amplitude of the first term.
This signal expression is defined only for 0 ≤ N ≤ Fs, which means it is valid within the given range of time steps. Elsewhere, outside this range, the signal is not defined.
Overall, K~2(N) represents a discrete-time signal composed of two sine waves with different frequencies and amplitudes, defined within a specific range of time steps.

For this assignment you will combine background reading and desktop research with information you gather during your field trip, to write a report on the Naboro Landfill. Conclusion [2 marks] Describe one thing you would change about the Naboro Landfill - either in terms of design, management or operation, which you think would improve it. Overall, does the Naboro Landfill contribute to sustainable development? Explain your answer.
A broader and integrated approach to waste management is necessary to fully address the challenges and opportunities associated with sustainable development in the context of the Naboro Landfill.
One thing that I would change about the Naboro Landfill to improve its design, management, and operation is the implementation of a comprehensive waste segregation and recycling system. Currently, the landfill primarily operates as a disposal site for mixed waste without much emphasis on waste separation or recycling. Introducing a well-structured waste segregation system would help divert recyclable materials from being buried in the landfill, reducing the volume of waste and prolonging the lifespan of the landfill.
By implementing waste segregation, the landfill could establish separate collection points for different types of recyclable materials such as plastics, paper, glass, and metals. This would enable these materials to be diverted to recycling facilities, where they can be processed and reused, thus reducing the overall environmental impact of waste disposal. Additionally, promoting recycling would create opportunities for employment and the development of a local recycling industry, further contributing to sustainable development.
Regarding the overall contribution of the Naboro Landfill to sustainable development, it currently falls short due to its limited focus on waste management and recycling. However, with the implementation of the suggested changes, the landfill has the potential to contribute significantly to sustainable development. By reducing the amount of waste being buried and promoting recycling, the landfill can minimize its environmental footprint, conserve natural resources, and support a circular economy.
It is important to note that achieving sustainable development requires a holistic approach that considers various factors such as social, economic, and environmental aspects. While the suggested change of implementing waste segregation and recycling would be a significant improvement, other measures, such as exploring alternative waste treatment technologies or promoting waste reduction at the source, should also be considered for a more comprehensive and sustainable waste management approach.
In conclusion, by introducing a waste segregation and recycling system, the Naboro Landfill can improve its operations and contribute to sustainable development by reducing the volume of waste, conserving resources, and fostering local recycling initiatives. However, a broader and integrated approach to waste management is necessary to fully address the challenges and opportunities associated with sustainable development in the context of the Naboro Landfill.

Design a square column footing for a 16-in. squared shape cross section tied column that
supports a dead load PD = 200 kip and a live load PL = 160 kip. The column is reinforced with
eight #8 bars, the base of the footing is 5 ft below grade, the soil weight is 100 lb/ft3, yy= 60,000
psi and cc′= 4000psi, normal weight concrete. Allowable bearing pressure for the soil is 5000 psf.
The designed square column footing for the given specifications is approximately 8.49 ft in side length, with a depth of 5 ft. The footing meets the allowable bearing pressure requirement, and proper reinforcement should be provided using eight #8 bars, appropriately detailed and spaced.
To design a square column footing, we need to consider the column loads, soil properties, and allowable bearing pressure. Here's a step-by-step approach to designing the footing:
Determine the total load on the column:
Total load = Dead load (PD) + Live load (PL)
Total load = 200 kip + 160 kip
Total load = 360 kip
Calculate the area of the footing required:
Footing area = Total load / Allowable bearing pressure
Footing area = 360 kip / (5000 psf * 1 kip / 1000 psf)
Footing area = 72 ft²
Determine the dimensions of the square footing:
Since it's a square footing, we can calculate the side length:
Side length = √Footing area
Side length = √72 ft²
Side length ≈ 8.49 ft
Determine the depth of the footing:
The base of the footing is given as 5 ft below grade. Hence, the depth of the footing will be 5 ft.
Check if the allowable bearing pressure is satisfied:
Calculate the actual bearing pressure:
Actual bearing pressure = Total load / Footing area
Actual bearing pressure = 360 kip / (8.49 ft * 8.49 ft)
Actual bearing pressure ≈ 5.03 ksf
The actual bearing pressure is within the allowable bearing pressure of 5 ksf, indicating that the design meets the requirements.
Determine the reinforcement requirements:
Since the column is reinforced with eight #8 bars, we need to ensure sufficient reinforcement within the footing. The reinforcement should be placed at the bottom of the footing to resist tension and provide bending moment resistance.
Ensure proper detailing and spacing of the reinforcement bars, considering the structural requirements and local building codes.
In summary, the designed square column footing for the given specifications is approximately 8.49 ft in side length, with a depth of 5 ft. The footing meets the allowable bearing pressure requirement, and proper reinforcement should be provided using eight #8 bars, appropriately detailed and spaced.

The periods of time when the unit is idle is called Stalls. The flow rate is controlled in centrifugal pump by Valve. The fluid coming in the centrifugal pump is accelerating with the help of impeller.
A centrifugal pump is a machine used to transfer fluids by the transformation of kinetic energy into hydrodynamic energy. These machines use a rotating impeller to raise the velocity of the fluid and then convert this into pressure head. As a result, centrifugal pumps are capable of converting mechanical energy into hydraulic energy.
A centrifugal pump works by the conversion of rotational kinetic energy into hydrodynamic energy, which occurs when an impeller accelerates fluid from the center of rotation to the outer edge of a rotating cylinder. The rotation of the impeller creates a suction force that causes fluid to enter the pump through an inlet nozzle, where it is then forced out the discharge nozzle by the impeller blades at a higher velocity than it entered the pump.In a centrifugal pump, flow is controlled by a valve, which is used to restrict or open the flow rate. When the valve is open, the flow rate is high, and when the valve is closed, the flow rate is low. The periods of time when the unit is idle is called Stalls.In a centrifugal pump, fluid comes in from the inlet nozzle, and the impeller accelerates the fluid with the help of impeller blades. This acceleration creates a centrifugal force that moves the fluid towards the outer edge of the rotating cylinder, where it is forced out the discharge nozzle.

If it is moved to a point right in front of the level at point A, readings change to 5.18 ft on A (which will be with no earth curvature error) and 6.76 ft on B (which will be with an error due to the earth curvature). What is the correct elevation difference between A and B? Also, find the error due to the earth curvature in reading on B when the rod was mover to point A? (10 points)
The correct elevation difference between points A and B is 1.57 ft. The error due to the earth curvature in the reading on B when the rod was moved to point A is 0.58 ft.
To find the correct elevation difference between A and B, we subtract the initial rod readings at A and B:
Elevation difference = Reading at B - Reading at A
Elevation difference = 7.91 ft - 6.29 ft
Elevation difference = 1.57 ft
Now, let's calculate the error due to earth curvature in the reading on B when the rod was moved to point A. The difference between the new reading at B and the reading at A gives us the error:
Curvature error = Reading at B (after movement) - Reading at A (after movement)
Curvature error = 6.76 ft - 5.18 ft
Curvature error = 0.58 ft
Therefore, the correct elevation difference between points A and B is 1.57 ft, and the error due to the earth curvature in the reading on B when the rod was moved to point A is 0.58 ft.

The array is initialized with 11 elements, corresponding to the possible values of 2 through 12. The element at index 0 represents the sum of 2, the element at index 1 represents the sum of 3, and so on.
To account for the fact that array indices start at 0, we subtract 2 from the sum when we store it in the array.After rolling the dice 100 times, the program prints the array of sums. To count how many times 12 appears, we access the element at index 10 (since 12 - 2 = 10). This gives us the count of 12s that were rolled.

It seems like storage is getting cheaper every year. Why not
just buy more storage?
Simply buying more storage without assessing actual needs and optimizing existing resources can lead to unnecessary expenses and inefficient storage management. It is crucial to consider scalability and data security.
While it is true that storage costs have been decreasing over the years, the decision to buy more storage should not be solely based on the premise that it is getting cheaper. There are several factors to consider before opting for more storage:
1. Cost vs. Need: Although storage costs have reduced, they still contribute to the overall budget. Buying more storage without a clear need or justification can lead to unnecessary expenses. It is important to assess the actual storage requirements and ensure that additional storage aligns with the organization's needs and growth projections.
2. Efficient Resource Utilization: Instead of indiscriminately buying more storage, organizations should focus on optimizing their existing storage infrastructure. This includes implementing data management strategies, such as data deduplication, compression, and archiving, to maximize the utilization of available storage resources.
3. Scalability and Flexibility: While expanding storage may seem like a quick solution, it is essential to evaluate the scalability and flexibility of the existing storage infrastructure. Investing in scalable storage solutions that can adapt to changing needs allows for efficient resource allocation and prevents overprovisioning.
4. Data Security and Compliance: Increasing storage capacity without considering data security and compliance requirements can lead to potential risks.
Organizations need to ensure that additional storage adheres to security standards, including encryption, access controls, and data backup strategies, to protect sensitive information and comply with regulations.
5. Data Management and Governance: Simply adding more storage without a robust data management and governance strategy can lead to data sprawl, making it challenging to locate and retrieve information efficiently. Implementing proper data classification, organization, and metadata management practices is crucial to effectively utilize and maintain the expanding storage environment.
In summary, while the decreasing cost of storage may seem enticing, it is important to assess actual storage needs, optimize existing resources, consider scalability and flexibility, address data security and compliance requirements, and implement effective data management strategies before deciding to buy more storage.

Consider the following signal f(t)=sin(2πt)+3sin(8πt)+cos(3nt). (a) (2 marks) What is the highest angular frequency present in the signal? What is the highest numerical frequency present in the signal? (b) (2 marks) What is the Nyquist rate of the signal? Did you use the angular or the numerical frequency? (c) (3 marks) If you sample this signal with sampling period T, which values of T satisfy the Nyquist requirement? Choose and fix one such T. (d) (3 marks) Suppose you sample a signal and pass it through a low-pass filter. What is the range of cutoff frequency Mo that can 0 be chosen in the low-pass filter to avoid aliasing and avoid signal loss? (e) (BONUS - 5 marks) Compute the Fourier series coefficient C of f(t).
Angular frequency is a measurement of how quickly an object or signal oscillates or rotates in a circular motion. It represents the rate of change of the angle with respect to time.
The answers are:
a) The highest numerical frequency present in the signal is 8.
b) The Nyquist rate should be at least twice the highest numerical frequency, which is 2 * 8 = 16.
c) Value of T that satisfies this requirement could be T = 1/32.
d) The range of cutoff frequency M₀ that can be chosen is 0 < M₀ ≤ 16.
e) Computing the Fourier series coefficients C of f(t) requires performing Fourier analysis on the signal.
(a) The highest angular frequency present in the signal can be determined by examining the coefficients of the trigonometric functions. In this case, the highest angular frequency is 8π.
To convert the angular frequency to numerical frequency, we use the formula: numerical frequency = angular frequency / (2π).
Therefore, the highest numerical frequency present in the signal is 8.
(b) The Nyquist rate of a signal is the minimum sampling rate required to accurately represent the signal without introducing aliasing. The Nyquist rate is determined by the highest numerical frequency present in the signal.
In this case, the highest numerical frequency is 8. Therefore, the Nyquist rate should be at least twice the highest numerical frequency, which is 2 * 8 = 16.
(c) To satisfy the Nyquist requirement, the sampling period T should be less than or equal to the reciprocal of the Nyquist rate. In this case, the Nyquist rate is 16, so the sampling period T should be less than or equal to 1/16.
One such value of T that satisfies this requirement could be T = 1/32.
(d) To avoid aliasing and signal loss when sampling and passing the signal through a low-pass filter, the cutoff frequency Mo of the low-pass filter should be less than or equal to half the sampling frequency.
The sampling frequency is the reciprocal of the sampling period T. In this case, T = 1/32, so the sampling frequency is 32.
Therefore, the range of cutoff frequency M₀ that can be chosen is 0 < M₀ ≤ 16.
(e) Computing the Fourier series coefficients C of f(t) requires performing Fourier analysis on the signal. However, without specific limits or constraints on the signal or time range, it is not possible to provide the exact values of the Fourier series coefficients.

Servlet with JDBC
1) In assignment 2 a database named BookDB was created with 3 tables. Write a servlet that lets the user input an ISBN and returns the title, author(s), and pages. The input form should be displayed using a "get" request, and the output page should be displayed using a "post" request. This is similar to the TimeForm example which also used get and post. The JDBC portion is similar to the SimpleRegistration example. 2) Below attached image gave an example of a JSP using a JavaBean to calculate loan payments. Using this example as a guide, create a similar JSP page that uses a JavaBean to compute postage for a package. The user should input length, width, height, weight, and zone. Dimensions are in inches. Weight is in pounds. The zone should be 1-4. The form input fields should be mapped to bean properties using the "*". The calculation should be as shown below. length x width x height: use 1 if less than 288, 1.5 if larger.
weight: use 1 if less than 10 pounds, 1.5 if larger.
zone: use the zone value as is
postage: $10 x dimension factor x weight factor x zone factor
For example, suppose the dimensions are 8x8x12, the weight is 15 pounds, the zone is 2.
Then the postage is $10 x 1.5 x 1.5 x 2 = $45
Call the 'calculatePostage()' method and display the result. This can be done with the help of EL (Expression Language).
1) Servlet with JDBC: To create a servlet that allows the user to input an ISBN and returns the title, author(s), and pages, follow the steps below:
Step 1: Create a web project using Eclipse, and then create a package named 'com.servlet' in the src folder.
Step 2: Copy the JDBC jar file and paste it into the project's WebContent/WEB-INF/lib folder.
Step 3: Create the necessary folders in the WebContent folder (for example, WebContent/css, WebContent/images, and so on).
Step 4: Create the HTML and JSP files and add them to the WebContent folder as needed. For example, create the "index.html" file in the WebContent folder, and then create a subfolder named 'WEB-INF'. Create a subfolder named 'jsp' inside 'WEB-INF'. Create a JSP file named "display.jsp" inside the 'jsp' folder.
Step 5: Create a servlet named 'DisplayServlet' inside the 'com.servlet' package. This servlet extends the HttpServlet class. The doGet() method will generate the input form, and the doPost() method will display the output.
Step 6: Define the database connection and SQL query in the 'DisplayServlet.' It's similar to the SimpleRegistration example.
2) Using this example as a guide, create a similar JSP page that uses a JavaBean to compute postage for a package. The user should input length, width, height, weight, and zone. Dimensions are in inches. Weight is in pounds. The zone should be 1-4. The form input fields should be mapped to bean properties using the "*". The calculation should be as shown below. length x width x height: use 1 if less than 288, 1.5 if larger. weight: use 1 if less than 10 pounds, 1.5 if larger. zone: use the zone value as is postage:
$10 x dimension factor x weight factor x zone factorFor example, suppose the dimensions are 8x8x12, the weight is 15 pounds, the zone is 2.
Then the postage is $10 x 1.5 x 1.5 x 2 = $45.
Here's how you can create a JSP page that calculates postage using a JavaBean:
Step 1: Create a web project in Eclipse, and then create a package named 'com.servlet' in the src folder.
Step 2: Create a JavaBean named 'PostageCalculationBean' in the 'com.servlet' package. It should have the following properties: length, width, height, weight, and zone. Use the 'double' data type for the dimensions and weight. Use the 'int' data type for the zone. It should also have a method named 'calculatePostage()'.
Step 3: Create the necessary folders in the WebContent folder (for example, WebContent/css, WebContent/images, and so on).
Step 4: Create the HTML and JSP files and add them to the WebContent folder as needed. For example, create the "index.html" file in the WebContent folder, and then create a subfolder named 'WEB-INF'. Create a subfolder named 'jsp' inside 'WEB-INF'. Create a JSP file named "postage.jsp" inside the 'jsp' folder.
Step 5: Inside the 'postage.jsp' file, import the 'PostageCalculationBean' class and create a new instance of it. Then, use the "setProperty" method to set the values of the length, width, height, weight, and zone properties.
Finally, call the 'calculatePostage()' method and display the result. This can be done with the help of EL (Expression Language).

Determine the range of K for which a system with the following characteristics equation is stable. s³ + 3Ks² + (K + 2)s + 4 = 0
The stability of a system can be determined by the characteristics equation of the system. A system is stable if all the roots of the characteristic equation have negative real parts. In this case, the given equation is a cubic equation whose roots will be complex conjugates or real.
In the case of complex conjugate roots, their real parts will be negative. It means that the system will be stable if the real parts of the roots are negative.
To determine the range of K for which a system with the given characteristics equation is stable, we will solve this equation using Routh-Hurwitz stability criterion and then check the conditions of this criterion. To apply the Routh-Hurwitz criterion, we will form a Routh array from the coefficients of the equation.
The Routh array is as follows: s³ 1 K + 2 0 3K0 K + 2 4 0 3KThe first column of the Routh array consists of the coefficients of s³, the second column consists of the coefficients of s², and so on. For this Routh array to ensure the stability of the system, all the elements in the first column must be positive, which means K + 2 > 0 and 3K > 0. Thus, the range of K for which the system is stable is -2 < K < 0.
Therefore, the range of K for which a system with the given characteristics equation is stable is -2 < K < 0.

Which of the following gives a cloud provider the ability to distribute resources on an as needed basis to the cloud consumer and in tum helps to improve efficiency and reduce costs? Select one:
a Elasticity b. Shared resources c. Infrastructure consolidation d. Network isolation
The correct answer is a) Elasticity. Elasticity in cloud computing refers to the ability of a cloud provider to dynamically allocate and scale computing resources based on the changing needs of the cloud consumer.
It allows the cloud provider to distribute resources on-demand, ensuring that the consumer has access to the required resources when they need them and only pays for what they use.
By leveraging elasticity, a cloud provider can optimize resource allocation and achieve higher efficiency. They can scale up resources during periods of high demand to meet increased workloads and scale them down during periods of low demand to avoid unnecessary costs.
This flexibility enables efficient resource utilization, as resources can be dynamically provisioned and deprovisioned based on real-time demands.
Elasticity also promotes cost reduction for both the cloud provider and the consumer. The provider can optimize infrastructure utilization by scaling resources up or down as needed, minimizing wasted resources and associated costs. The consumer, on the other hand, benefits from paying only for the resources they actually use, rather than investing in fixed infrastructure.
In summary, elasticity gives cloud providers the ability to distribute resources on an as-needed basis, improving efficiency, and reducing costs by dynamically allocating resources based on the changing demands of the cloud consumer.
So, option a is correct.

Figure 2, shows the convolution systems consisting of the input, x(t), output response, y(t), and the impulse response, h(t). The convolution of the input, x(t), and the impulse response, h(t) produces the output response, y(t). Sometimes the convolution integral is difficult to solve analytically in the time domain. By using the property, the output response can be obtained by using the Continuous-Time Fourier Transform (CTFT). In simple words, the convolution between two signals in the time domain is equivalent to the multiplication of the CTFTs of the two signals in the frequency domain. Based on that, if x(t) = eu(t) and h(t) = e-2tu(t) verify the results of the output response, y(t) = (e-t-e-2t)u(t) using the CTFT approach. x(1)- h(1) Y(0) Figure 2
The output response, y(t), can be verified using the Continuous-Time Fourier Transform (CTFT) approach for the given input signal x(t) = eu(t) and impulse response h(t) = e[tex]^{-2tu(t)}[/tex].
The CTFT approach allows us to determine the output response, y(t), by multiplying the CTFTs of the input signal, X(jω), and the impulse response, H(jω), in the frequency domain.
To apply the CTFT approach, we need to find the CTFTs of x(t) and h(t). The CTFT of x(t) is X(jω), which is a constant value of 1/(jω+1) in this case. The CTFT of h(t) is H(jω), which is a constant value of 1/(jω+2).
Multiplying X(jω) and H(jω) gives us the CTFT of the output response, Y(jω), which is (1/(jω+1))*(1/(jω+2)). To obtain y(t) in the time domain, we need to inverse CTFT Y(jω) to get y(t).
By performing the inverse CTFT, we can verify that the output response, y(t), is indeed given by y(t) = ([tex]e^{-t}[/tex]. - [tex]e^{-2t}[/tex])u(t), which matches the result stated in the question.
Using the CTFT approach simplifies the convolution operation by transforming it into a multiplication in the frequency domain, which can be more convenient and computationally efficient, especially for complex or time-consuming convolution calculations.
