a) The line current that the circuit operates on is 10∠270°. b) The load impedance is 11∠330°.

Given data; A balanced delta – connected load has a phase current IAC = 10∠30° A.

The formula for calculating phase current (Iph) is:

Iph = IAC

If IAC = 10∠30°, then the phase current is:

Iph = 10∠30°.

a) Since the circuit is balanced, the line currents can be calculated by using the following formula;

Iab = Ica = Iph

Ibc = Iac = Iph∠-120°

Ica = Iab = 10∠30°

Ibc = 10∠(30°-120°)=10∠-90° = 10∠270°.

b) The formula for calculating line voltage (VL) is:

VL = √3 × VphIf

Vab = 110∠0°, then the line voltage is:

VL = √3 × Vph= √3 × 110 = 190.5V.

If Iab = 10∠30° and Vab = 110∠0°, then the load impedance can be calculated using the following formula;

Zab = Vab/Iab

Zab = 110∠0° / 10∠30°= 11∠-30° = 11∠330°

a) From the given figure, the transfer function of the system is:

$$H(z)=\frac{z^{-1}}{1-1.5 z^{-1}+0.7 z^{-2}}$$

For the input signal,

$$x(t)=te^{-t}u(t)$$

Taking the z-transform,

$$X(z)=\frac{1}{(1-z^{-1})^2}$$

Using the above transfer function and z-transform of the input signal, the output signal is calculated as follows:

$$\begin{aligned} Y(z)&=X(z)H(z) \\ &=\frac{1}{(1-z^{-1})^2} \cdot \frac{z^{-1}}{1-1.5 z^{-1}+0.7 z^{-2}} \\ &=\frac{0.33 z^{-1}}{(1-0.6 z^{-1})^2} +\frac{0.67}{1-0.6 z^{-1}} \end{aligned}$$

Using partial fraction expansion, the above equation can be written as follows:

$$Y(z)=\frac{0.33}{1-0.6 z^{-1}}+ \frac{0.27}{(1-0.6 z^{-1})^2}+\frac{0.4}{1-0.4 z^{-1}}$$

Taking the inverse z-transform, the output signal y(n) is:

$y(n)=0.33\cdot (0.6)^n u(n)+0.27\cdot n\cdot (0.6)^n u(n)+0.4\cdot (0.4)^n u(n)$$

Taking the inverse Laplace transform, the output signal y(t) is:

$$y(t)=\frac{1}{5} \left(e^{-t}-\cos(2t)+\frac{1}{2} \sin(2t)\right)u(t)$$

Thus, the output signal y(t) is obtained.

```

In this code, the `swapVectors` function takes two vector references as input parameters. It first checks if the vectors have the same size. If they don't, an error message is displayed, and the function returns early. Otherwise, a temporary vector `temp` is created to hold the contents of the first vector. The contents of the first vector are then replaced with the contents of the second vector, and finally, the contents of the second vector are replaced with the contents of `temp`, effectively swapping the contents of the two vectors.

In the `main` function, we create two vectors `vec1` and `vec2` with the given elements. We print the contents of the vectors before and after the swapping using a loop. Finally, we call the `swapVectors` function to swap the vectors and print the contents again to verify the swap.

Q1(a) Losses and power flow of an induction motor

The three-phase induction motor has three stator winding phases displaced by 120 degrees in space and is wound on the stator poles.

The rotor of the motor is wound on the rotor poles and is supplied by AC power from the stator winding that induces a current in the rotor winding.

The power flow and losses are illustrated in the below diagram:

(i) At no-load, the rotor runs at a speed equal to the synchronous speed because the rotor is not loaded with any torque, so it does not slip.

As a result, the rotor speed of 1350 r/min is equal to the synchronous speed (Ns) at a frequency of 50 Hz.

(ii) At full load, the rotor has a slip of 11.11%, which is calculated as follows:

Slip, s = (Ns - N) / Ns

Where,

Ns = 120

f/P = 120 × 50/4

= 1500 r/min

N = full-load speed

= 1200 r/mins

= (1500 - 1200) / 1500

= 0.2

The electrical frequency of the rotor at no-load is 50 Hz, and at full-load, it is 45 Hz.

Since the rotor frequency is proportional to the slip, we can calculate the rotor frequency at no-load and full-load as:

f1 = (1 - s) × f

= (1 - 0) × 50

= 50 Hz

f2 = (1 - s) × f

= (1 - 0.2) × 50

= 40 Hz

(iii) Speed regulation of the motor can be calculated as follows:

Speed regulation,

R = (N1 - N2) / N2 × 100%

Where, N1 = no-load speed

= 1350 r/min

N2 = full-load speed

= 1200 r/min

R = (1350 - 1200) / 1200 × 100%

= 12.5%

Therefore, the speed regulation of the motor is 12.5%.

The maximum achievable channel utilization for Stop-and-Wait protocol can be calculated as 1 / (1 + 2a), where 'a' represents the propagation delay in terms of transmission time.

In Stop-and-Wait protocol, the sender transmits a frame and waits for an acknowledgment before sending the next frame. The channel utilization can be calculated as the ratio of the time spent transmitting data frames to the total time, including transmission and waiting time In this scenario, the frames have a size of 5000 bits and are sent over a 2 Mbps channel. The transmission time for each frame can be calculated as (frame size / channel bandwidth). Thus, the transmission time for a 5000-bit frame is 5000 bits / (2 Mbps) = 0.0025 seconds. The propagation time from the earth to the satellite is given as 270 ms. To convert this to transmission time, we divide it by the frame transmission time, resulting in 270 ms / 0.0025 s = 108 frames. Since acknowledgments are piggybacked onto data frames, the acknowledgment transmission time is negligible compared to the data frame transmission time. The maximum achievable channel utilization can be calculated using the formula: 1 / (1 + 2a), where 'a' represents the propagation delay in terms of transmission time. In this case, a = 108 (number of frames). Plugging in the value of 'a' into the formula, we get: 1 / (1 + 2 * 108) ≈ 1 / 217 ≈ 0.0046. Therefore, the maximum achievable channel utilization for Stop-and-Wait protocol in this scenario is approximately 0.0046, or 0.46%.

The given closed-loop transfer function of a negative unity feedback system is: T(s) = S³ + 1/ 254 + s² + 2s. Now, we need to find the systems using Routh-Hurwitz Criterion for Stability. Routh-Hurwitz Criterion The Routh-Hurwitz criterion is used to determine whether a closed-loop control system is stable or unstable. It is simple to use and avoids the need to solve a high-order polynomial.

Routh-Hurwitz criterion can only be used for systems whose transfer function has real coefficients. To construct a Routh-Hurwitz table, follow the instructions below: Make a table with two rows and as many columns as the highest-order term in the polynomial. The second row should contain only the coefficients of the even powers of the polynomial. The first row should contain only the coefficients of the odd powers of the polynomial.

The coefficients should be written in descending order. If any coefficient is absent, substitute zero for it. The first column should contain the coefficients of the highest-order and the second column should contain the coefficients of the next-highest order. If the leading coefficient in the first column is zero, replace it with a small nonzero value ε. The first two rows of the table are used to compute the remaining rows. The values in the remaining rows are computed as follows: Each element in a given row is computed by taking the determinant of the 2×2 submatrix formed by the two coefficients in the column to the left of the element and the two coefficients in the row above the element, divided by the value in the first column of the row directly above the element.

If any of the elements in a row are zero or have a zero divisor in the first column, the remaining elements in that row and all rows below it are also zero. If all of the elements in the first column are either positive or negative, the system is stable. If there are any sign changes in the first column, the number of sign changes is equal to the number of poles of the system in the right half of the s-plane. If there are any poles in the right half of the s-plane, the system is unstable. If there are any sign changes in the first column, but no poles in the right half of the s-plane, the system is marginally stable.

(a) With a page offset of 26 bits, the number of possible pages is 2^6 = 64. (b) The addresses of the first three frames in physical memory would depend on the specific mapping scheme used. (c) The smallest space that could be allocated for a page table would depend on the number of pages and the page table entry size. (d) With a 256-entry page table and a logical address space of 48 bits, each physical memory frame must be 48 - log2(256) = 48 - 8 = 40 bits.

(a) To calculate the number of pages possible, we need to subtract the number of bits used for the page offset from the total number of bits in the logical address space. In this case, we have a logical address space of 32 bits and a page offset of 26 bits. So, the number of possible pages is 2^(32-26) = 2^6 = 64. (b) The addresses of the first three frames in physical memory would depend on the specific mapping scheme used. Without additional information or a specific mapping scheme, it is not possible to determine the exact addresses of the first three frames. (c) The smallest space allocated for a page table would depend on the number of pages and the page table entry size. Since we have 64 possible pages (as calculated in part (a)), the minimum space needed for the page table would be the number of pages multiplied by the size of each page table entry. (d) With a 256-entry page table and a logical address space of 48 bits, we can calculate the size of each physical memory frame. We subtract the number of bits needed to represent the page table entry (log2(256) = 8 bits) from the total number of bits in the logical address space. So, each physical memory frame must be 48 - 8 = 40 bits.

The given system is described by: y(n)= 5x(n-10)where y(n) and x(n) are the output and input signals of the system respectively. Based on the given information, the following will determine if the system is linear, time-invariant and causal:

Linearity: A system is said to be linear if it satisfies the superposition and homogeneity properties. Superposition means that the output of the system due to the sum of two input signals is the sum of the output of the system due to each input signal. Homogeneity means that the output of the system due to a constant multiple of the input signal is the same as the constant multiple of the output of the system due to the input signal. Using the given system, let: x1(n) and x2(n) be two input signals, y1(n) and y2(n) be the corresponding output signals, and a1 and a2 be any two constants. Thus, we have: y1(n) = 5x1(n-10), and y2(n) = 5x2(n-10).Consider the superposition property: y3(n) = a1y1(n) + a2y2(n) y3(n) = a15x1(n-10) + a25x2(n-10) y3(n) = 5(a1x1(n-10) + a2x2(n-10)). This shows that the system is linear.

Time-invariance: A system is time-invariant if its input-output relationship does not change over time. Thus, the output of the system due to a delayed input signal should be equal to the delayed output signal of the system due to the original input signal. Using the given system, let x(n-T) be a delayed input signal, where T is a constant delay. Thus, we have: y1(n) = 5x(n-T-10) y1(n) = 5x(n-(T+10). The above equation shows that the system is time-invariant since the output of the system due to the delayed input signal is equal to the delayed output signal of the system due to the original input signal.

Causality: A system is causal if its output depends only on the present and past values of the input signal and not on the future values of the input signal. Using the given system, y(n) = 5x(n-10), we observe that the output signal y(n) depends only on the present and past values of the input signal x(n).

Thus, the system is causal. Therefore, based on the above explanations, the given system is linear, time-invariant, and causal.

The percent total harmonic distortion of the amplifier is approximately 21.9%.

To calculate the percent total harmonic distortion (THD) of an amplifier, we need to determine the ratio of the sum of all harmonics to the fundamental frequency.

In this case, the fundamental frequency is 21,100 Hz. The output signal contains several harmonic frequencies, including:

Second harmonic at 42,200 Hz with a magnitude of 0.25 and phase angle of -30 degrees

Third harmonic at 63,300 Hz with a magnitude of 2.5 and phase angle of -70 degrees

Fifth harmonic at 105,500 Hz with a magnitude of 0.5 and phase angle of -130 degrees

To calculate the THD, we first need to calculate the total harmonic distortion (THD) factor, which is defined as the root mean square (RMS) sum of all harmonic components divided by the RMS value of the fundamental frequency component.

The RMS value of the fundamental frequency component can be calculated using:

Vrms = Vp / sqrt(2)

where Vp is the peak voltage of the fundamental frequency component. In this case, the peak voltage of the fundamental frequency component is 12.0 V, so the RMS voltage is:

Vrms = 12.0 / sqrt(2) = 8.49 V

Next, we calculate the RMS sum of all harmonic components. For each harmonic, we first need to calculate its RMS voltage:

Vh_rms = Vh_p / sqrt(2)

where Vh_p is the peak voltage of the harmonic component.

For the second harmonic (42,200 Hz):

Vh_p = 0.25 V

Vh_rms = 0.25 / sqrt(2) = 0.177 V

For the third harmonic (63,300 Hz):

Vh_p = 2.5 V

Vh_rms = 2.5 / sqrt(2) = 1.77 V

For the fifth harmonic (105,500 Hz):

Vh_p = 0.5 V

Vh_rms = 0.5 / sqrt(2) = 0.354 V

Now we can calculate the RMS sum of all harmonic components as:

Vh_sum_rms = sqrt(V2_2nd_h + V2_3rd_h + V2_5th_h)

where V2_2nd_h is the square of the RMS voltage of the second harmonic component, V2_3rd_h is the square of the RMS voltage of the third harmonic component, and V2_5th_h is the square of the RMS voltage of the fifth harmonic component.

Plugging in the values, we get:

Vh_sum_rms = sqrt((0.177)^2 + (1.77)^2 + (0.354)^2) = 1.857 V

Finally, we can calculate the THD factor as:

THD_factor = Vh_sum_rms / Vrms = 1.857 / 8.49 = 0.219

The percent total harmonic distortion is then given by:

THD_percent = THD_factor x 100% = 0.219 x 100% = 21.9%

Therefore, the percent total harmonic distortion of the amplifier is approximately 21.9%.

CFL contains the class DCFL (Deterministic Context-Free Languages). CFL is contained within the class RL (Regular Languages).

The computational complexity class CFL, which stands for Context-Free Languages, is a class of languages that can be recognized by a non-deterministic pushdown automaton (PDA) or equivalently by a context-free grammar. Context-free languages are a type of formal language that can be generated by rewriting rules where a non-terminal symbol can be replaced with a sequence of terminal and non-terminal symbols.

One class contained within CFL is the class of regular languages (RL). Regular languages can be recognized by deterministic finite automata (DFA) or non-deterministic finite automata (NFA). Regular languages have simpler grammar rules compared to context-free languages, and their languages can be described by regular expressions.

One class that CFL contains is the class of deterministic context-free languages (DCFL). Deterministic context-free languages are a subset of context-free languages where every production rule in the grammar has a unique expansion for each non-terminal symbol. DCFLs can be recognized by deterministic pushdown automata, which are PDAs with the restriction that they can only have one possible transition for each input symbol and top of the stack symbol.

   else:

       print("Invalid road name!")

       return

   # Check if the speed exceeds the speeding limit, accounting for the 20 km/h margin

   if speed > (speeding_limit + 20):

       print("You will incur a speeding fine!")

   else:

       print("You are within the speed limit.")

# Prompt the user for input

speed = int(input("Enter your speed (in km/h): "))

road = input("Enter the road name: ")

# Call the function to check for speeding

check_speeding(speed, road)

The given information is for an RC series circuit. The goal is to find the source impedance that maximizes the average power dissipated in the series RC load.

Source Impedance Zs is given by,Zs = R + j(ωC)Now, for the power dissipated in the RC load, we have,

Power, P = VI (cosθ)Here, V is the RMS value of the voltage across the RC load, I is the RMS current through the RC load, and cosθ is the phase angle between voltage and current.Now, V = V0∠0° (open-circuit voltage) and I = V0/Zs (voltage drop across the RC circuit)

Hence, P = (V0^2/Zs) (cosθ)Substituting the value of Zs in the above equation, we get,P

= (V0^2/R)[cosθ/(1 + (ωCR)^2)]To maximize the power dissipated, we need to maximize P. This can be done by maximizing cosθ/(1 + (ωCR)^2).To maximize cosθ/(1 + (ωCR)^2), we need to minimize (ωCR)^2. This means that the impedance across the RC circuit must be kept small. For this, the value of C must be kept large. The lower the impedance across the RC circuit, the greater the power dissipation will be.

Thus, the expression for the source impedance that maximizes the average power dissipated in the series RC load is Zs = R + j(ωC). The RC circuit impedance should be kept low for maximum power dissipation. Formula used: Source Impedance Zs = R + j(ωC)Power, P = VI (cosθ)Hence, P = (V0^2/Zs) (cosθ)P = (V0^2/R)[cosθ/(1 + (ωCR)^2)]
