To determine the type of the system, we need to find the number of poles at the origin (i.e., the number of integrators) in the open-loop transfer function.
The open-loop transfer function, G(s), has three poles at the origin (s² term in the denominator). Hence, the system is a Type 3 system.
Now let's calculate the steady-state error for each input using the steady-state error formula:
1. For the input 80u(t):
The steady-state error, E(s), is given by E(s) = 1 / (1 + G(s)). Since the input is a step function (u(t)), we can substitute s with 0 in the transfer function.
E(s) = 1 / (1 + G(0))
E(s) = 1 / (1 + 60(34)(4)(8) / (0)(6)(17))
Since there is an integrator in the system, the steady-state error for a step input is zero (E(s) = 0).
2. For the input 80tu(t):
The steady-state error, E(s), is given by E(s) = 1 / (1 + G(s)) * 1/s. We can substitute s with 0 in the transfer function.
E(s) = 1 / (1 + G(0)) * 1/0
E(s) = ∞
The steady-state error for a ramp input is infinity.
3. For the input 80t²u(t):
The steady-state error, E(s), is given by E(s) = 1 / (1 + G(s)) * 1/s². We can substitute s with 0 in the transfer function.
E(s) = 1 / (1 + G(0)) * 1/0²
E(s) = ∞
The steady-state error for an acceleration input is also infinity.
In summary:
For a step input (80u(t)), the steady-state error is 0.For a ramp input (80tu(t)), the steady-state error is infinity (∞).For an acceleration input (80t²u(t)), the steady-state error is also infinity (∞).The complete question should be:
[tex]80t^{2}u(t)[/tex]
For a unity feedback system with feedforward transfer function as
[tex]G(s)\frac{60(s+34)(s+4)(s+8)}{s^{2}(s+6)(s+17)}[/tex]
The type of system is:

Your programming project will be create a C-string variable that contains a name, age, and title. Each field is separated by a space. For example, the string might contain "Bob 45 Programmer" or any other name/age/title in the same format. Assume the name, age, and title have no spaces themselves. Write a program using only functions from cstring (not the class string) that can extract the name, age, and title into separate variables. Test your program with a variety of names, ages, and titles. Once you have completed this task, repeat the prompt, with the exception of using the class string to extract the fields and not the cstring functions.
Direction: (Language usage of C++, do not use pointers, and have user input for multiple test cases)
In order to extract the name, age, and title from a C-string variable containing a name, age, and title, follow these steps: Step 1: Create a C-string variable and initialize it with name, age, and title separated by spaces. Let's name this C-string variable `person`.
Step 2: Declare three character arrays, `name`, `age`, and `title`, each with sufficient length to store their respective field values.Step 3: Use the `strtok()` function from the cstring library to extract the first token from the `person` string. Since the fields are separated by spaces, the delimiter for this function will be a space.
Store the result in the `name` array.
Step 4: Call `strtok()` again to extract the next token, which will be the `age`. Store this value in the `age` array.
Step 5: Call `strtok()` one more time to extract the final token, which will be the `title`. Store this value in the `title` array.
Step 6: Print out the values of the `name`, `age`, and `title` arrays to verify that the values were extracted correctly. Here is the code that implements the above algorithm in C++:#include
To test the program with different inputs, simply change the value of the `person` string. For example: char person[] = "Alice 25 Manager" ;char person[] = "John 35 Engineer" ;Now, to repeat the prompt using the class string instead of the cstring functions, simply replace the C-string variables with string objects.

Specify a baseband Nyquist channel which has a piecewise linear amplitude response, an absolute bandwidth of 10 kHz, and is appropriate for a baud rate of 16 kbaud. What is the channel’s excess bandwidth?
A baseband Nyquist channel with a piecewise linear amplitude response and an absolute bandwidth of 10 kHz that is appropriate for a baud rate of 16 kbaud can be specified as follows:Sampling theorem states that a signal can be sampled at a rate that is equal to or greater than twice the bandwidth of the signal.
The Nyquist rate is equal to two times the signal bandwidth, which is [tex]2×10 kHz = 20 kbps[/tex].The channel's symbol rate is given as 16 kbaud, which is equal to 16,000 symbols per second. Therefore, each symbol occupies [tex]1/16,000 = 62.5 μs[/tex].Using piecewise linear amplitude response, the channel's bandwidth should be flat up to the Nyquist frequency of 20 kbps and have zero bandwidth beyond that limit.
This bandwidth is exactly equal to the signal bandwidth, i.e., 10 kHz.The excess bandwidth of the channel is calculated using the following formula:
[tex]$$\mathrm{Excess\ bandwidth} =\frac{\text{Channel bandwidth}-\text{Signal bandwidth}}{\text{Signal bandwidth}}=\frac{10-20}{20}=-0.5=-50\%$$[/tex]

Explain the impact of increasing the DFT length to 18.
Given are the two signals x1 and x2 of length 8 such that,Signal x1 is 1 for the first L samples, where L = 4, 5, 6, 7, and 8, and 0 for any remaining samples. That means x1 is a step signal.Signal x2 is 1 for the first 3 samples and 0 for 5 samples. That means x2 is an impulse signal(a.) For each of the values of L, convolve xl and x2 to produce y and sketch a stem plot of the result of each convolution.
The convolution is given by the formula: $y[n] = \sum_{k=-\infty}^{\infty} x_1[k]x_2[n-k]$Length of the convolution signal y can be given by Length of x1 + Length of x2 - 1Length of y = 8 + 8 - 1 = 15Length of x1 = 8 and Length of x2 = 8For L = 4, Length of x1 = 8, L = 4 means 1 for first 4 samples and 0 for next 4 samples. That means only the first 4 samples are non-zero.
The convolution y will be a signal of length 15 having 4 non-zero samples which are the first 3 and 8th sample of y. The stem plot for this signal will be:For L = 5, Length of x1 = 8, L = 5 means 1 for first 5 samples and 0 for next 3 samples. That means only the first 5 samples are non-zero. .The point by point multiplication of X1' and X2' and then taking an inverse DFT to get y2 is given by: X1' = fft(x1', 18) X2' = fft(x2', 18) Y2 = X1'.*X2' y2 = ifft(Y2)The stem plot of the y2 signal is as follows:By comparing the above stem plot with the stem plot obtained in part (a) for L = 4, we can see that the values are the same. This is because when the length of the DFT increases, the frequency response also becomes better and hence the convolution result using DFT becomes similar to the result obtained from convolution in time domain.

Using Buckingham's theorem, develop an expression that gives the distance traveled () in time T by a freely falling body, assuming that the distance depends on the weight of the body (W), the acceleration due to gravity (), and of time (T)
Please, make the steps to make clearly understand.
Buckingham's Theorem is a general technique that may be utilized to analyze problems.
The technique reduces the number of variables in the issue by determining the number of dimensionless groups necessary to define the problem.
The objective of the Buckingham Pi theorem is to evaluate and define a physical situation using the principle of dimensional homogeneity.
The statement of Buckingham’s theorem is that "if there are n variables in a dimensional equation and m fundamental dimensions, then the equation can be expressed in terms of (n-m) independent dimensionless groups.
"Let's develop an expression that gives the distance traveled () in time T by a freely falling body, assuming that the distance depends on the weight of the body (W), the acceleration due to gravity (), and of time (T).
Here, the three variables W, g, and T can be grouped using Pi groups.
The first step in the application of Buckingham's theorem is to identify the relevant dimensions that are necessary to solve the problem:
Length, LTime, T Mass, M
We know that the gravitational force experienced by an object is given by
F = ma.
The weight of an object can be given as
F = W
= mg.
Thus, it can be concluded that:
Force, F = Mass, M * Acceleration,
L / T2 [Force, F] = [Mass, M] * [Acceleration, L / T2]
= M * L / T2
F = W
= M * g [Force, F]
= [Mass, M] * [Acceleration due to gravity, L / T2]
= M * L / T2
Now, we'll use Buckingham Pi theorem to group the variables.
According to the Buckingham Pi theorem,
The number of dimensionless Pi groups is given by the number of variables (n) minus the number of fundamental dimensions (m).
We have 3 variables (W, g, T) and 3 fundamental dimensions (L, M, T), hence we will have zero dimensionless groups.
Now, we have to find a way to express distance using a combination of the variables.
The formula for distance is given as
S = ½ * g * T2
W = M * g
Therefore,
g = W / M
Replacing the value of g in the equation for distance, we get,
S = ½ * (W / M) * T2
S = (W / 2M) * T2
Thus, the distance traveled (S) by a freely falling body is given by (W / 2M) * T2, assuming that the distance depends on the weight of the body (W), the acceleration due to gravity (), and time (T).

The distance between two points is measured with a total station EDM. The precision of the EDM is stated to be ±(1 mm + 1.5 ppm). The recorded distance is 320.252 m. What is the precision of this measurement? [5 marks]
The precision of the measurement recorded by the total station EDM is ±0.001480378 m.
To determine the precision of the measurement recorded by the total station EDM, we need to calculate the maximum allowable error or uncertainty.
The precision of the EDM is stated as ±(1 mm + 1.5 ppm), where ppm stands for parts per million. To calculate the precision, we need to convert the ppm value to meters.
1 ppm = 1/1,000,000
1.5 ppm = 1.5/1,000,000 = 0.0000015
Now, let's calculate the precision using the recorded distance of 320.252 m.
Precision = ±(1 mm + 0.0000015 * recorded distance)
= ±(0.001 m + 0.0000015 * 320.252 m)
= ±(0.001 m + 0.000480378 m)
= ±0.001480378 m
Therefore, the precision of the measurement recorded by the total station EDM is ±0.001480378 m.
It's important to note that precision refers to the degree of repeatability or consistency in measurements and represents the range within which the actual value is expected to fall. This precision value indicates that the recorded distance of 320.252 m has an uncertainty of ±0.001480378 m, meaning the true distance is expected to lie within the range of 320.25052 m to 320.25348 m.

Part 1 Create a class called Student to hold individual Student information that includes: name - (String) - the full name of the student id (int) - The student id major - (String) - The major of the student gpa (double) - The grade point average of the student classOf (int) - Projjected graduation year Add getters and setters for the 5 members of the class. The President asks for a report of all students and he wants it sorted by 2 criteria: Major and Gpa. Specifically, he says 'please sort it by descending Gpa within Major'. Note that this is a tiered sort with 2 criteria. So all of the students with the same major are together in the sorted list. Within the groups of students for a specific major (i.e. CS, TSM, etc), that group is sorted by descending Gpa. You can start with the Selection Sort code provided in Selection.java. However, your task is to craft a compareTo() method that will properly sort the students by the double criteria.
Sort algorithm is required reports for enrolled students at the University, a class called Student should be created to store individual student information such as name, ID number, major, GPA, and projected graduation year. This class should also include a custom compareTo() method to properly sort the students based on the specified criteria of major and GPA.
To meet the requirements of generating sorted reports for enrolled students, a class named Student needs to be implemented. This class should have private member variables for storing the student's name, ID number, major, GPA, and projected graduation year. Additionally, getter and setter methods should be provided for accessing and modifying these member variables.
To achieve the tiered sorting criteria specified by the President, a custom compareTo() method needs to be implemented in the Student class. This compareTo() method should compare the major of two students first. If the majors are different, the students should be sorted based on their majors in ascending order. However, if the majors are the same, the method should compare the students' GPAs in descending order. This way, all students with the same major will be grouped together in the sorted list, and within each major group, the students will be sorted by descending GPA.
By implementing the Student class and the compareTo() method as described, the Registrar's office will be able to generate reports that fulfill the President's requirements for sorting by major and GPA. The reports will provide a clear and organized view of enrolled students, facilitating analysis and decision-making processes.

G(s) = R (s) / (1 + L(s)) = 5.173 / [1 + 5.173(S+3)/S(S+0.1333)]
The transfer function can be simplified as shown below :
G(s) = 5.173S / (0.1333S² + 0.7209S + 5.173)
Now, we can obtain the values of damping ratio (ζ) and undamped natural frequency (ωn) as shown below :
ζ = 0.37ωn = 5.17 rad/s
Using the obtained value of ζ, we can determine the value of MPO as shown below :
MPO = (100 × e^(−ζπ/√(1 − ζ²))%)
MPO = (100 × e^(−0.37π/√(1 − 0.37²))%)
MPO = 9.3%

According to the question ( a ) The resulting grammar in CNF is: S → X1X2 , A → aA , X1 → A , X2 → bB
, bbB ( b ) Greibach normal form S → AbB | bbB , A → aA , B → bbB | b
(a) Conversion to Chomsky Normal Form (CNF):
Step 1: Eliminate ε-productions
We don't have any ε-productions in the given grammar, so no changes are required for this step.
Step 2: Eliminate unit productions
The grammar doesn't contain any unit productions, so no changes are needed here.
Step 3: Convert terminals
In this step, we'll convert each terminal into a non-terminal. Since all the terminals in the given grammar are already in the form of single characters, no changes are required.
Step 4: Convert long productions
We have two long productions: S → AbB and bbB. Let's convert them.
S → AbB
| A → aA
| AbB → AbB
| bbB → bbB
The production S → AbB can be rewritten as follows:
S → X1X2
X1 → A
X2 → bB
After this step, the grammar becomes:
S → X1X2
A → aA
X1 → A
X2 → bB
bbB
Step 5: Convert binary productions
The grammar is now in the form where each production has at most two non-terminals or a terminal. Therefore, no further changes are required to convert it into Chomsky normal form (CNF).
The resulting grammar in CNF is:
S → X1X2
A → aA
X1 → A
X2 → bB
bbB
(b) Conversion to Greibach Normal Form (GNF):
To convert the grammar to Greibach normal form, we need to ensure that the right-hand side of each production starts with a terminal. However, the given grammar already satisfies this condition, so no changes are required.
The resulting grammar in Greibach normal form (GNF) is the same as the original grammar:
S → AbB | bbB

II.4 What are the MIPS assembly instruction described above?
I. IntroductionMIPS, an acronym for Microprocessor without Interlocked Pipeline Stages, is a computer hardware architecture that has been in use since 1981. It was created by researchers at Stanford University, including John L. Hennessy and Edward S. Davidson.
MIPS processors are used in a variety of embedded systems, such as routers and modems, as well as personal computers. II. SolutionII.1 We know that the R-type instruction is used to manipulate the contents of registers. The opcode, rs, rt, rd, shamt, and funct fields are used to specify the instruction's format.
The I-type instruction, on the other hand, is used to manipulate the memory and register contents. The opcode, rs, rt, and constant fields are used to specify the instruction's format.II.2 For the first instruction: aop = 0, rs = 1, rt = 2, rd = 3, shamt = 0, funct = 0x20Since it uses all six fields (opcode, rs, rt, rd, shamt, and funct), it is an R-type instruction.
II.3 For the second instruction: bop = 0x2B, rs = 0x10, rt = 5, constant = 0x4Since it uses four fields (opcode, rs, rt, and constant), it is an I-type instruction.II.4 The MIPS assembly instruction for the first instruction would be ADD $3, $1, $2. The MIPS assembly instruction for the second instruction would be SW $5, 0x4($10).Hence, the R-type instruction is ADD $3, $1, $2 and the I-type instruction is SW $5, 0x4($10).

Given the frequency response of the LTI: 1+2e + -jw +e-2/w H(e)= a. Obtain the impulse response of the LTI system. b. Obtain the difference equation of the LTI system. c. Draw the block diagram to represent this system.
The impulse response of the LTI system is h[n] = (1/3)(δ[n] + 2δ[n-1] - δ[n-2]). The difference equation of the LTI system is y[n] = x[n] + 2x[n-1] - x[n-2]. Block diagram representation is not provided.
To obtain the impulse response of the LTI system, we need to find the inverse Z-transform of the given frequency response H(e). The frequency response can be written as H(e) = 1 + 2[tex]e^{-jw}[/tex] + e[tex]^{-2jw}[/tex]. Taking the inverse Z-transform of each term separately, we get h[n] = δ[n] + 2δ[n-1] - δ[n-2]. Here, δ[n] represents the unit impulse function or the Kronecker delta.
The difference equation describes the relationship between the input signal x[n] and the output signal y[n] of an LTI system. By analyzing the impulse response, we can deduce the difference equation. From the impulse response h[n] = (1/3)(δ[n] + 2δ[n-1] - δ[n-2]), we can see that the current output y[n] is the sum of the current input x[n], twice the previous input x[n-1], and the negation of the input two steps ago x[n-2]. Therefore, the difference equation for the LTI system is y[n] = x[n] + 2x[n-1] - x[n-2].

b) Explain and discuss the correlation of UPV in terms of compressive strength anf concrete quality?
c) Explain and discuss possible errors leading to unsatisfactory results. What are the modifications that might help to resolve these errors?
d) Explain observations on how w/c, admixtures and puzzolans influenced the strength of concrete?
Smooth surfaces are needed on cubes for compressive strength testing to ensure uniform load distribution during the test.
Irregular surfaces or imperfections can lead to stress concentration points, resulting in premature failure or inaccurate strength readings. Smooth surfaces help minimize these local stress concentrations and provide a more reliable measurement of the concrete's compressive strength.
If cylinders were used instead of cubes, the strength reading may differ. Cylinders generally exhibit slightly lower compressive strength compared to cubes due to differences in stress distribution and specimen geometry. Conversion factors can be used to relate the strength results between cubes and cylinders, but it is important to consider the specific conversion factors applicable to the testing standards being followed.

(10P) Solve the question by clearly writing all steps of mathematical operations with correct notation and specifying all formulas and units.
The Gauss's theorem, sometimes referred to as the divergence theorem or simply as the divergence theorem, The divergence theorem's formula is as follows:∮S F · dA = ∭V (∇ · F) dV
Surface integral:
∮S D · dA = ∮S f(cosθ)²sinθ/1³ · dA
We can split the surface integral into two parts: the outer shell (S₂) and the inner shell (S₁).
∮S D · dA = ∮S₁ D · dA + ∮S₂ D · dA
Using the proper surface area element, dA = r2sindd, where r is the radial distance, is the polar angle, and is the azimuthal angle, it is possible to calculate the surface integrals for the outer and inner shells.
∮S D · dA = ∮S₁ f(cosθ)²sinθ/1³ · r₁²sinθdθdФ + ∮S₂ f(cosθ)²sinθ/1³ · r₂²sinθdθdФ
After integrating over the angles θ and Ф, the expression simplifies to:
∮S D · dA = ∫[θ=0→π] ∫[Ф=0→2π] f(cosθ)²sin²θ/1³ · r₁²sinθdθdФ + ∫[θ=0→π] ∫[Ф=0→2π] f(cosθ)²sin²θ/1³ · r₂²sinθdθdФ
Volume integral:
∭V (∇ · D) dV = ∭V (∇ · [f(cosθ)²sinθ/1³]) dV
Using spherical coordinates, the divergence operator ∇ · D can be expressed as:
∇ · D = (1/r²) ∂(r²D_r)/∂r + (1/(r sinθ)) ∂(sinθD_θ)/∂θ + (1/(r sinθ)) ∂D_ϕ/∂ϕ
After expanding and simplifying the expressions, the volume integral becomes:
∭V (∇ · D) dV = ∫[r=r₁→r₂] ∫[θ=0→π] ∫[ϕ=0→2π] [(1/r²) ∂(r²D_r)/∂r + (1/(r sinθ)) ∂

A system response h(n) has the following Fourier transform: H(ω)=1−0.25e−jω1 Determine the Fourier transforms of the following signals where, x(n)=cos(0.3πn) i) h(n)∗x(n) ii) h(n)∗x(n−1)
The Fourier transforms are as follows:
For h(n) * x(n): Y(ω) = 0.5[δ(ω - 0.3π) + δ(ω + 0.3π)] - 0.125e^(-jω).For h(n) * x(n-1): Y'(ω) = π[δ(ω - 0.3π) + δ(ω + 0.3π)] - 0.25πe^(-jω)[δ(ω - 0.3π) + δ(ω + 0.3π)].To determine the Fourier transforms of the given signals, we will utilize the properties of the Fourier transform.
Given:
H(ω) = 1 - 0.25e^(-jω)x(n) = cos(0.3πn)i) To find the Fourier transform of h(n) * x(n):
Using the property of the Fourier transform for convolution:
H(ω) * X(ω) = Y(ω)
where * denotes convolution and Y(ω) represents the Fourier transform of the convolution of h(n) and x(n).
First, let's find the Fourier transform of x(n):
X(ω) = 0.5[δ(ω - 0.3π) + δ(ω + 0.3π)]
Next, we convolve H(ω) and X(ω) to obtain the Fourier transform of the convolution:
Y(ω) = H(ω) * X(ω)
= (1 - 0.25e^(-jω)) * (0.5[δ(ω - 0.3π) + δ(ω + 0.3π)])
= 0.5[δ(ω - 0.3π) + δ(ω + 0.3π)] - 0.25e^(-jω) * 0.5[δ(ω - 0.3π) + δ(ω + 0.3π)]
Simplifying the expression:
Y(ω) = 0.5[δ(ω - 0.3π) + δ(ω + 0.3π)] - 0.125e^(-jω)[δ(ω - 0.3π) + δ(ω + 0.3π)]
ii) To find the Fourier transform of h(n) * x(n-1):
For this case, we need to introduce a time shift in x(n) by substituting n-1 in the expression:
x(n-1) = cos(0.3π(n-1))
Using the property of the Fourier transform for time shifting:
FT{cos(αn)} = π[δ(ω - α) + δ(ω + α)]
The Fourier transform of x(n-1) becomes:
X'(ω) = π[δ(ω - 0.3π) + δ(ω + 0.3π)]
Now, we can perform the convolution of H(ω) and X'(ω):
Y'(ω) = H(ω) * X'(ω)
= (1 - 0.25e^(-jω)) * π[δ(ω - 0.3π) + δ(ω + 0.3π)]
= π[δ(ω - 0.3π) + δ(ω + 0.3π)] - 0.25e^(-jω) * π[δ(ω - 0.3π) + δ(ω + 0.3π)]
Simplifying the expression:
Y'(ω) = π[δ(ω - 0.3π) + δ(ω + 0.3π)] - 0.25πe^(-jω)[δ(ω - 0.3π) + δ(ω + 0.3π)]
Therefore, the Fourier transforms of the given signals are as follows:
i) Fourier transform of h(n) * x(n):
Y(ω) = 0.5[δ(ω - 0.3π) + δ(ω + 0.3π)] - 0.125e^(-jω
ii) Fourier transform of h(n) * x(n-1):
Y'(ω) = π[δ(ω - 0.3π) + δ(ω + 0.3π)] - 0.25πe^(-jω)[δ(ω - 0.3π) + δ(ω + 0.3π)]

In TDM communication, to transmit 10 voice signals, bandlimited to 5kHz using PAM, the system bandwidth should be 50kHz. The TDM approach assigns different time slots to the signals so that they are transmitted one after the other.
Pulse Amplitude Modulation (PAM) is a modulation technique that transmits signals in analog form. PAM converts the continuous amplitude of the message signal into a series of discrete amplitudes. PAM is a method for transmitting signals via time-division multiplexing (TDM). Each signal is transmitted for a specific amount of time, known as a time slot. As a result, each signal is transmitted one after the other. In this problem, we are to transmit ten 5 kHz voice signals using PAM, thus the system bandwidth should be 50 kHz. Therefore, for a successful TDM communication, the system bandwidth should be equal to or greater than the sum of the bandwidth of all the signals to be transmitted.

The task is to implement the given function f = La.b,c (1,4,6) using a multiplexer. Multiplexers are digital circuits that can select and route digital signals from multiple input sources onto a single output.
A multiplexer can be used to implement the given function f = La.b,c (1,4,6) using the following steps:
Firstly, determine the number of input signals required for implementing the function.
In this case, three input signals are required as there are three variables a, b, and c involved in the function.
The multiplexer should have 3 select lines and 2³ = 8 input lines since there are three variables involved in the given function.
It means that for the function to work, the multiplexer should have 3 select lines, and 8 input lines.
Since there are 3 select lines, they can be used to select any one of the eight input signals to be passed to the output. For example, if the value of a is 0, b is 0, and c is 0, the input signal 0 will be selected by the multiplexer.
Similarly, if the value of a is 1, b is 0, and c is 1, the input signal 5 will be selected. The output signal will be the selected input signal.
The given function f = La.b,c (1,4,6) can be implemented using a 3:8 multiplexer, where the inputs to the multiplexer are as follows:
Input 0: a=0, b=0, c=0
Input 1: a=0, b=0, c=1
Input 2: a=0, b=1, c=0
Input 3: a=0, b=1, c=1

_avg = (1/T) ∫P(t) dtwhere P(t) is the instantaneous power and T is the time period.I ntegrating P(t) with respect to t, we get, = (1/T) ∫P(t) dt = (1/T) ∫[-2565 cos 50t + 4434.87 sin 50t] dtP_avg = (-2565/T) ∫cos 50t dt + (4434.87/T) ∫sin 50t dtP_avg = (-2565/T) (1/50 sin 50t) + (4434.87/T) (-1/50 cos 50t)P_avg = (-51.3/T) sin 50t + (88.7/T) cos 50tP_avg = (-51.3/2π) sin (2π/T) t + (88.7/2π) cos (2π/T)
tSubstituting the value of
T=1/50, we get,P_avg = -1000/19 sin (1000/19) t + 1750/19 cos (1000/19)
tTherefore, the average power isP_avg = -1000/19 sin (1000/19) t + 1750/19 cos (1000/19) t Ans: Instantaneous power: P = -2565 cos 50t + 4434.87 sin 50tAverage power: P_avg = -1000/19 sin (1000/19) t + 1750/19 cos (1000/19) t.
