Expected value When you roll a fair dice, you have an even chance to roll each of the six numbers from 1 to 6. The expected value of your dice roll is 3.5. But how can this be? This number is not even on the dice! In probability theory, expectation or expected value is an idealized mean that reflects the probability of something's possible outcomes. In our dice example, each of the six numbers has a one-sixth probability of rolling. This means that if you roll the dice many and many times, approximately 1 out of six on all rolls, 2 in roughly all rolls, 2 on all rolls, 3 on all rolls, and so on. It means you have to see. So if you rolled the dice n times and rounded each number times, each of the numbers would come roughly once. Therefore, the number you get when averaging all the results of rolling the dice is roughly (n/6x1+n/6x2+n/6x3+n/6x4+n/6×5+n/6×6) (1+2+3+4+5+6)/6 3.5. is equal to a. The strong law of large numbers says that the larger the number, the closer the true mean to 3.5. The number 3.5 is, in a sense, the average you would get if you rolled the dice an infinite number of times. The same idea is true more generally. Let's assume your dice is not fair, so not all six numbers are equally likely to come up. The proba- bility of getting 1, the probability of getting 2, etc. Let's assume it is.

When a fair dice is rolled, it has an equal chance of rolling each of the six number from 1 to 6. The expected value of the dice roll is 3.5.
This is the idealized mean that reflects the probability of something's possible outcomes. The number 3.5 is not even on the dice. It means if a dice is rolled many times, approximately 1 out of 6 rolls, the number 1 will come up, 2 in roughly 1 out of 6 rolls, and so on.
If the dice is rolled n times and each number times are rounded, each of the numbers would come roughly once. Therefore, the number you get when averaging all the results of rolling the dice is roughly (n/6x1+n/6x2+n/6x3+n/6x4+n/6×5+n/6×6) (1+2+3+4+5+6)/6 = 3.5.The general definition of expectation is that if a random variable has up to m possible outcomes and corresponding probabilities up to Pi, the expected value of the outcome E=P₁ x X₁ +P₂ x X₂+ +Pm X m. The question is to find out what the expected value is for the sum of the faces of a dice that is rolled n times. The expected value for one roll is 3.5.
Thus, the expected value for n rolls is n x 3.5 = 3.5n.A MATLAB program that finds the expected value of the dice roll experiment can be written as follows: For a single dice roll: rolls = 1;exp_val = mean (6, 1, rolls))For n dice 1000;rolls = (6, n, 1) mean(sum(rolls, 2))The MATLAB code above will simulate rolling a dice once and find the expected value of that roll. For n dice rolls, it will simulate the rolls and find the sum of the faces for each roll. It will then take the mean of the sum of the faces for all the rolls to find the expected value of the dice roll experiment.

Structures are a group of members, such as beams, columns, slabs, foundations, girders, and trusses, that work as a unit to fulfil a purpose. An engineer's duty is to design structures in a professional, safe, and economical manner to fulfil the purpose for which it was designed in the first place. Structures as classified into either being statically determinate or statically indeterminate Please explain in detail with the examples and application classification of Statically determinate structures and statically indeterminate structures. [PLO1; CLO1:C3) (60 Marks)
Statically determinate structures and statically indeterminate structures are two classifications used in structural engineering to describe the behavior and analysis of different types of structures.
Statically determinate structures are those in which the equilibrium conditions can be completely determined by considering the external loads and the internal forces within the structure. The number of unknown reactions and internal forces can be calculated using the principles of statics alone. In other words, the internal forces and deformations of each member can be determined by solving a set of simultaneous equilibrium equations. Examples of statically determinate structures include simply supported beams, trusses, and frames with pinned connections.
The application of statically determinate structures is widespread in engineering. Simple beam structures, such as those found in bridges and buildings, can often be analyzed using basic principles of statics. The loads on the structure, such as dead loads (weight of the structure itself) and live loads (occupancy, wind, or seismic loads), can be easily determined, and the internal forces and reactions can be calculated accordingly. The design of statically determinate structures is relatively straightforward, as the internal forces and stresses can be determined precisely.
On the other hand, statically indeterminate structures are those in which the number of unknown reactions and internal forces exceeds the number of available equilibrium equations. The equilibrium conditions alone cannot determine the internal forces and deformations of each member. Additional equations are required, such as compatibility equations based on the deformation characteristics of the materials. Examples of statically indeterminate structures include continuous beams, arches, and frames with fixed connections.
The analysis and design of statically indeterminate structures are more complex and require advanced engineering methods. Techniques such as moment distribution method, slope-deflection method, and matrix analysis are used to solve the additional equations and determine the internal forces and deformations. Statically indeterminate structures have advantages in terms of increased load-carrying capacity and better distribution of stresses. They are often used in long-span bridges, high-rise buildings, and structures subjected to dynamic loads.
In summary, the classification of structures into statically determinate and statically indeterminate categories is based on their behavior and analysis complexity. Statically determinate structures can be analyzed using basic principles of statics, while statically indeterminate structures require additional equations and advanced analysis methods. Both types of structures have their applications and play important roles in engineering design, depending on the specific requirements and constraints of the project.

If we change load/store instructions to use a register (without an offset) as the address, these instructions no longer need to use the ALU. As a result, the MEM and EX stages can be overlapped and the pipeline has only four stages. (a) (5 pts) How will the reduction in pipeline depth affect the clock cycle time? (b) (5 pts) How might this change reduce the number of stalls of the pipeline? (c) (5 pts) How might this change degrade the performance of the processor?
The reduction in pipeline depth will affect the clock cycle time positively. Shortening the clock cycle time indicates that the instructions can be executed quicker in a shorter time.
It reduces the number of stalls of the pipeline because the use of registers eliminates the dependencies which would result in stalls. The stalls lead to low performance and the processor may be slowed down to compensate. This enables the instructions to run smoothly in the MEM and EX stages.
The change could lead to the reduction of performance of the processor. This is because the change makes the processor lose the ability to efficiently perform operations that need constant communication between the registers and memory, like moving large memory blocks. Thus, this may cause performance degradation which might cause the processor to become slower.

Glucose (C6H12O6) is converted to gluconic acid (C6H12O7) by an enzymatic reaction. In the reaction, glucose, water and O2 are the reactants; gluconic acid and hydrogen peroxide (H2O2) are products. In the balanced reaction, each five chemicals have a stoichiometric coefficient of 1.
A mixture containing 6% glucose, 22% water, and the rest unreactive particles is pumped to a bioreactor at a rate of 2800 kg/h continuously. Air is supplied to the bioreactor in a way that 45 kg oxygen are delivered per hour. The desired glucose level in the product leaving the bioreactor is 0.3%. Determine the composition of the off-gas leaving the bioreactor.
[MWglucose= 180; MWgluconic acid= 196; MWO2= 32; Air composes 23.3% O2 and 76.7% N2 by weight]
The balanced chemical equation of the reaction is as follows: C6H12O6 + 2O2 + H2O → C6H12O7 + H2O2The main answer to the question is that the composition of the off-gas leaving the bioreactor is 4.6% O2 and 95.4% N2 by volume.
First, let's determine the rate of glucose entering the bioreactor. The total flow rate is given as 2800 kg/h, and the mixture contains 6% glucose by weight. Therefore, the mass flow rate of glucose is:2800 kg/h × 6/100 = 168 kg/hNext, we need to determine the oxygen requirement for the reaction. The balanced equation tells us that 1 mole of glucose reacts with 2 moles of oxygen, so the stoichiometric ratio of oxygen to glucose is 2/180 (or 1/90) by mass. Therefore, the mass flow rate of oxygen required for the reaction is:168 kg/h × 1/90 = 1.87 kg/hThe air supplied to the bioreactor contains 23.3% oxygen by weight.
Therefore, the mass flow rate of air required to deliver 1.87 kg/h of oxygen is:1.87 kg/h ÷ 0.233 = 8.03 kg/hThe off-gas leaving the bioreactor must contain all of the unreacted nitrogen from the air, but none of the oxygen. Therefore, the composition of the off-gas by weight is:100% - 23.3% = 76.7% N2 by weightThe molecular weight of nitrogen is 28, so the mass fraction of nitrogen is:76.7% ÷ 28 = 2.738 g/molThe molecular weight of air is approximately 28.96, so the mass fraction of air that is nitrogen is:2.738 g/mol ÷ 28.96 g/mol = 0.0944The mass flow rate of air required to deliver 1.87 kg/h of oxygen is:1.87 kg/h ÷ (0.233 × 0.0944) = 86.1 kg/hTherefore, the off-gas leaving the bioreactor contains 76.7% N2 and 23.3% air by weight. The composition of the off-gas by volume is calculated as follows:The molar volume of an ideal gas at standard conditions (0 °C, 1 atm) is approximately 24 L/mol, so the volume flow rate of air required to deliver 1.87 kg/h of oxygen is:1.87 kg/h × 1000 g/kg ÷ 28.96 g/mol × 24 L/mol = 1960 L/hThe volume flow rate of the off-gas is the same as the air flow rate, which is 1960 L/h. Therefore, the volume composition of the off-gas is:23.3% × 1960 L/h = 456 L/h of air76.7% × 1960 L/h = 1504 L/h of N2Therefore, the composition of the off-gas by volume is 4.6% O2 and 95.4% N2 by volume.

To conceptualize a solution to convert a 4-bit input (binary) to the equivalent decimal value using a PIC and 2 multiplexed 7-segment displays, we need to follow some assumptions and steps. Firstly, we assume that the four-bit input will come from an external source and will be provided as input to our PIC.
A flowchart for the solution to convert a 4-bit input (binary) to the equivalent decimal value using a PIC and 2 multiplexed 7-segment displays is shown below:Assuming that the binary input is present at the input of the PIC, we first initialize all the PORTs as per the PIC architecture. The binary input is then read and stored in a variable. Now, we can convert this binary number to a decimal number. The decimal value will be displayed using two multiplexed 7-segment displays.
To convert the binary value to decimal, we need to multiply the bits with their respective weights, starting from the rightmost bit, and then add the products. The weight of the rightmost bit will be 2⁰, and the weight of the leftmost bit will be 2³. The formula for conversion is:Decimal value = b3*2³ + b2*2² + b1*2¹ + b0*2⁰Where, b3, b2, b1, and b0 are the four bits of the binary input, with b3 being the leftmost bit (most significant bit) Each digit is then displayed on one of the two 7-segment displays by multiplexing. The change in the binary value will initialize the change in the display output by following the above steps.

Given that an analog non-periodic signal f is given by etf(t) = < t, e^t < 0 0 ≤ t ≤ π/2.
e^(π/2−t), π/2 < t ≤ π.
The Fourier transform of f(t) is given by,
F(f(t)) = F(f(t)) = ∫[0,∞) f(t) e^-jωt dt....
(1)The given function is etf(t) = < t, e^t < 0 0 ≤ t ≤ π/2.
e^(π/2−t), π/2 < t ≤ π.
Rewriting the function, f(t) = t, 0 ≤ t ≤ π/2.
f(t) = e^(t−π/2), π/2 < t ≤ π.
Therefore, the Fourier transform of f(t) is
F(f(t)) = ∫[0,π/2] f(t) e^-jωt dt + ∫[π/2,∞) f(t) e^-jωt dt
Putting the values of f(t) in the above equation, we get
∫[0,π/2] t e^-jωt dt + ∫[π/2,∞) e^(t−π/2) e^-jωt dt
Integrating both sides with respect to t, we get
F(f(t)) = -jω(π/2) e^(-jωπ/2) + 1/(jω)^2 e^(-jωπ/2) + (1/(jω) − π/2) e^(-jωπ/2)
Again, simplifying the above equation, we get
F(f(t)) = -jω(π/2) e^(-jωπ/2) + (1/(jω))^2 e^(-jωπ/2) + (1/(jω) − π/2) e^(-jωπ/2)
F(f(t)) = e^(-jωπ/2) (1/(jω))^2 − jω(π/2 + 1/(jω) − π/2)
F(f(t)) = e^(-jωπ/2) (1/(jω))^2 − (jω/(jω)^2 )
F(f(t)) = -j (1/(ω^2)) + (1/ω) e^(-jωπ/2)
Hence, the Fourier transform of f(t) is given by -j (1/(ω^2)) + (1/ω) e^(-jωπ/2).

(b). Find the energy associated with the energy signal given by x(t)=e^-4t u(t) and verify Parseval's theorem using x(t)
(a) Parseval's theorem is a tool used to determine the total energy in a signal. This theorem is usually applied in Fourier analysis and signal processing. The theorem indicates that if we have an orthonormal system, then we can find the total energy of a signal through a summation of all the Fourier coefficients.
Parseval's theorem states that for a function f(x) with the Fourier transform F(w), the energy E of f(x) is defined by:E = 1/2π ∫_-∞^∞ |f(x)|^2 dx = 1/2π ∫_-∞^∞ |F(w)|^2 dw
Now, we have to prove Parseval's theorem. We can show that Parseval's theorem is correct by taking the following steps:
Step 1: Assume that f(x) is a function with the Fourier transform F(w).
Step 2: Define the energy E of f(x) by:E = 1/2π ∫_-∞^∞ |f(x)|^2 dx
Step 3: Calculate the Fourier series coefficients for f(x). The coefficients are given by:cn = 1/2π ∫_-∞^∞ f(x) e^(-i n x) dx
Step 4: Calculate the total energy of f(x) in terms of the Fourier coefficients. We have:E = Σ |cn|^2
Step 5: Substitute the Fourier coefficients into the total energy equation. We have:E = 1/2π ∫_-∞^∞ |f(x)|^2 dx = Σ |cn|^2
Step 6: Simplify the right-hand side of the equation. We have:E = 1/2π ∫_-∞^∞ |F(w)|^2 dwThus, we have proved Parseval's theorem. This theorem shows that we can calculate the total energy of a signal in terms of its Fourier coefficients.
Parseval's theorem is an important tool in Fourier analysis and signal processing. The theorem allows us to calculate the total energy of a signal in terms of its Fourier coefficients. We can prove the theorem by taking a few steps, including assuming that f(x) is a function with the Fourier transform F(w), defining the energy E of f(x) by E = 1/2π ∫_-∞^∞ |f(x)|^2 dx, and calculating the total energy of f(x) in terms of its Fourier coefficients. Finally, we substitute the Fourier coefficients into the total energy equation, and we simplify the equation to show that E = 1/2π ∫_-∞^∞ |F(w)|^2 dw.
(b) The energy signal is given by x(t) = e^-4t u(t), where u(t) is the unit step function. We can calculate the total energy of x(t) using Parseval's theorem. The energy E of x(t) is given by:E = 1/2π ∫_-∞^∞ |X(w)|^2 dwWe can find the Fourier transform of x(t) by using the formula:X(w) = ∫_-∞^∞ x(t) e^(-i w t) dt. We can substitute x(t) into the Fourier transform formula to obtain:X(w) = ∫_-∞^∞ e^-4t u(t) e^(-i w t) dt
We can simplify this expression by using the following identity: u(t) = ∫_-∞^∞ δ(t) dt, where δ(t) is the Dirac delta function.
X(w) = ∫_-∞^∞ e^-4t ∫_-∞^∞ δ(t - τ) e^(-i w τ) dτ dtX(w) = ∫_-∞^∞ e^(-i w τ) ∫_-∞^∞ e^-4t δ(t - τ) dt dτX(w)
= ∫_-∞^∞ e^(-i w τ) e^-4τ dτX(w) = 1/(i w + 4)
We can substitute X(w) into the energy equation to obtain:
E = 1/2π ∫_-∞^∞ |X(w)|^2 dwE = 1/2π ∫_-∞^∞ |1/(i w + 4)|^2 dwE = 1/2π ∫_-∞^∞ 1/(w^2 + 16) dwE = 1/16π [arctan(w/4)]_-∞^∞E = 1/16π (π/2 + π/2)E = 1/8
Thus, the total energy of x(t) is 1/8.
We can find the total energy of an energy signal by using Parseval's theorem. We can apply the theorem to x(t) = e^-4t u(t) by finding its Fourier transform and substituting it into the energy equation. The total energy of x(t) is 1/8.

Length of vector C is therefore √194. (approximately 13.93 units)b) Unit vector in the A direction A vector is said to be a unit vector when its magnitude is equal to 1. To find the unit vector in the A direction, we can use the formula as follows: Unit vector in the A direction is given by A / |A|where |A| represents the magnitude of A.The magnitude of A is given by: Magnitude of A=√1² + 2² + 3²=√1 + 4 + 9=√14Unit vector in the A direction,
Therefore, is: A / |A| = [1, 2, 3] / √14To simplify it, we divide each of the coordinates of A by its magnitude: Unit vector in the A direction is approximately [0.267, 0.535, 0.802].

Let A and B two matrices, write a Python3 function to calculate the subtraction of these two matrices (A-B =?) (No Numpy!)
It initializes a new matrix C of the same dimensions as A and B. Finally, it subtracts the corresponding elements of A and B and stores the result in C. To calculate the subtraction of two matrices A and B, we simply need to subtract the corresponding elements of the matrices.
The result of the subtraction will be stored in a new matrix C, where each element c[i][j] is equal to a[i][j] - b[i][j].
Below is to write a Python3 function to calculate the subtraction of two matrices (A-B =?) without using numpy library:
```pythondef matrix_subtraction(A, B):
rows_A, cols_A = len(A), len(A[0]) rows_B, cols_B = len(B), len(B[0])
if rows_A != rows_B or cols_A != cols_B: raise
("Matrices must have the same dimensions") C = [[0 for j in range(cols_A)] for i in range(rows_A)] for i in range(rows_A): for j in range(cols_A): C[i][j] = A[i][j] - B[i][j] return C```
This function takes two matrices A and B as input and returns a new matrix C which is the result of the subtraction A - B. The function first checks if the dimensions of the matrices A and B are equal. If they are not equal, it raises an exception. Otherwise, it initializes a new matrix C of the same dimensions as A and B. Finally, it subtracts the corresponding elements of A and B and stores the result in C.

Which of the studied data structures in this course would be the most appropriate choice for the following tasks? And Why? To be submitted through Turnitin. Maximum allowed similarity is 15%. a. An Exam Center needs to maintain a database of 3000 students' IDs who registered in a professional certification course. The goal is to find rapidly whether or not a given ID is in the database. Hence, the speed of response is very important; efficient use of memory is not important. No ordering information is required among the identification numbers. b. A transposition table is a cache of previously seen positions in a game tree generated by a computer game playing program. If a position recurs via a different sequence of moves, the value of the position is retrieved from the table, avoiding re-searching the game tree below that position.
For maintaining the database of 3000 student IDs, the most appropriate data structure in this course would be hashing. Hashing is a technique that enables direct access to a record using a key and is an appropriate choice.
We want to search a large number of items (more than 100).Hashing is the best data structure for fast data searching because it provides an O(1) constant time to access, insert, or delete elements. It makes use of a hash function that maps large or non-numeric keys into smaller, more numeric keys that are used as indexes to access the data.
Since the speed of response is crucial in this scenario, hashing is the most appropriate data structure because it offers constant-time searching, which means it is the quickest.b.

const app = express()
app.use(bodyParser.urlencoded({ extended: true }))
app.use(bodyParser.json())
app.get('/api/employees', (req, res) => {
sql.query('SELECT * FROM Employees', (err, result) => {
if (err) console.log(err)
res.send(result)
})
})
app.post('/api/employees', (req, res) => {
sql.query(`INSERT INTO Employees VALUES ('${req.body.name}', ${req.body.age}, '${req.body.gender}')`, (err, result) => {
if (err) console.log(err)
res.send(result)
})
})
app.put('/api/employees/:id', (req, res) => {
sql.query(`UPDATE Employees SET Name = '${req.body.name}', Age = ${req.body.age}, Gender = '${req.body.gender}' WHERE ID = ${req.params.id}`, (err, result) => {
if (err) console.log(err)
res.send(result)
})
})
app. delete ('/api /employees/: id', (req, res) => {
sql.query(`DELETE FROM Employees WHERE ID = ${req.params .id}`, (err, result) => {
if (err) console.log(err)
res.send(result)
})
})
app.listen(3000, () => console.log('Server started'))
Step 3: Create a React Component to Consume the API
import React, { Component } from 'react'
import axios from 'axios'
class EmployeeList extends Component {
state = {
employees: []
}
componentDidMount() {
axios.get('/api/employees')
.then(res => {
this.setState({ employees: res.data })
})
}
render() {
return (
)
}
}
export default EmployeeList
Note: This is just an example code, and it is recommended to use proper validation and error handling before deploying it in a production environment. Express.js is a popular web application framework for Node.js that makes it easy to build APIs, which can be used to connect to the database and perform CRUD operations.

If we are given 4 distinct keys, how many different Binary Search trees (BSTs) can we construct? Explain. Hint: If we are given 3 distinct keys, there are 5 different BSTs.
If we are given 4 distinct keys, the number of different Binary Search Trees (BSTs) that can be constructed is 14. This can be explained as follows:First, we need to understand the logic behind the number of different BSTs that can be constructed given n distinct keys.
If we are given n keys, we know that there are n! (n factorial) ways of arranging them. However, this is not the main answer as we cannot construct all these arrangements as BSTs. In order for an arrangement to be a valid BST, we must ensure that the elements are arranged in a way such that the left subtree contains keys smaller than the root and the right subtree contains keys larger than the root.
In other words, we need to ensure that the BST property is maintained.To find the number of different BSTs that can be constructed given n distinct keys, we can use the following formula: Number of BSTs = (2n)! / [(n + 1)! * n!]Applying this formula to the case of 4 distinct keys, we get:Number of BSTs = (2 * 4)! / [(4 + 1)! * 4!]Number of BSTs = 40320 / (5 * 24)Number of BSTs = 14Therefore, we can construct 14 different BSTs given 4 distinct keys.

where:
- EI is the flexural rigidity of the beam (product of the modulus of elasticity E and the moment of inertia I)
- w(x, t) is the transverse deflection of the beam at position x and time t
- ρ is the mass density of the beam material
- A is the cross-sectional area of the beam
- d^4w/dx^4 represents the fourth derivative of the deflection with respect to the longitudinal coordinate x
- d^2w/dt^2 represents the second derivative of the deflection with respect to time t
43. Eigenvalue problems can be classified into two main types:
- Algebraic Eigenvalue Problems: In this type, the problem involves finding the eigenvalues (also known as characteristic values) and corresponding eigenvectors of a square matrix. The matrix equation involved is of the form Av = λv, where A is the matrix, λ represents the eigenvalue, and v is the eigenvector. The algebraic eigenvalue problems arise in various fields, including linear algebra, physics, and engineering.
- Differential Eigenvalue Problems: In this type, the problem involves finding the eigenvalues and eigenfunctions of a differential equation. The differential equation involved is of the form L(u) = λu, where L is a linear differential operator, λ represents the eigenvalue, and u is the eigenfunction. Differential eigenvalue problems are commonly encountered in areas such as quantum mechanics, vibration analysis, and heat conduction.
46. There are several methods used for solving transient vibration problems, which involve the analysis of vibrating systems under time-varying loads or initial conditions. Some commonly used methods include:
- Time Integration Methods: These methods involve numerically integrating the equations of motion over a time interval. Examples include the Euler method, Runge-Kutta methods, and Newmark's method. These methods approximate the solution at discrete time steps and can handle a wide range of transient loading conditions.
- Laplace Transform Method: This method involves transforming the equations of motion from the time domain to the Laplace domain, where the problem can be solved algebraically. After obtaining the solution in the Laplace domain, an inverse Laplace transform is applied to obtain the solution in the time domain. The Laplace transform method is particularly useful for problems with piecewise constant or periodic forcing functions.
- Modal Analysis: This method involves decomposing the system into its natural modes of vibration and solving for the modal response. The modal superposition principle is then used to obtain the complete solution by combining the modal responses. Modal analysis is particularly effective for problems with repeated or periodic loading conditions.
These methods provide different approaches to solving transient vibration problems, and the choice of method depends on the specific characteristics of the problem and the available computational resources.

Explain The Significance Of Poles And Zeros In General I.E., What Do Their Presence And Position Indicate?
Poles and zeros are important concepts in signal processing and control theory. They are critical in understanding the behavior of linear systems. In this context, a pole is a point where the transfer function of a system approaches infinity, while a zero is a point where the transfer function of a system becomes zero.
These points provide information about the behavior of a system, including its stability, frequency response, and impulse response. The significance of poles and zeros in general can be explained as follows:
1. Stability: The presence of poles in the right half of the complex plane indicates that the system is unstable. However, if all the poles are located in the left half of the complex plane, then the system is stable.
2. Frequency response: The location of poles and zeros in the complex plane has a significant effect on the frequency response of the system. The poles of the transfer function are responsible for the resonances in the frequency response, while the zeros are responsible for the notches or dips.
3. Impulse response: The location of poles and zeros also provides information about the impulse response of a system. The poles are responsible for the decaying or increasing behavior of the response, while the zeros are responsible for the oscillatory behavior of the response.
In general, the presence and position of poles and zeros in a system provide critical information about its behavior. They provide insight into the stability, frequency response, and impulse response of a system.
