An appropriate subnet addressing scheme can be designed by allocating 8 bits for subnetting within the Class B address space for 200 LANs, or by allocating a minimum of 1 Class C address for each LAN if Class C addresses are used.

In the given scenario, we have an organization with 200 local area networks (LANs), and each LAN has 120 hosts. We need to design an appropriate subnet addressing scheme using Class B and Class C addresses.

(i) Designing subnet addressing scheme with a Class B address:

To accommodate 200 LANs, we can use subnetting within the Class B address space. Since Class B provides 16 bits for the network portion, we can allocate 8 bits for subnetting. This would allow us to create 256 subnets, which is sufficient for 200 LANs. Each subnet can have up to 254 hosts (2^8 - 2).

(ii) Allocating Class C addresses:

If the organization is allocated Class C addresses, we need to determine the minimum number of Class C addresses required. Since each Class C address can accommodate only 254 hosts, we would need at least 200/254 = 0.79 Class C addresses. Since we cannot have a fraction of an address, we would need a minimum of 1 Class C address to accommodate 200 LANs.

In terms of an appropriate subnet addressing scheme, if we choose Class C addresses, we can assign one Class C address to each LAN, ensuring that each LAN has its own network address and can support up to 254 hosts.

The low-side DC-DC buck converter operates in continuous conduction mode for the full input voltage operating range. The duty cycle required to maintain a 5V output voltage is approximately 50% for both the maximum and minimum input voltages.

In continuous conduction mode, the current flowing through the inductor (iL) never reaches zero during the switching cycle. This mode is suitable for applications where the output power demand remains relatively constant.

During the maximum input voltage, the buck converter operates by turning on the high-side switch, allowing current to flow through the inductor and store energy. When the high-side switch turns off, the energy stored in the inductor is transferred to the output through the diode. The voltage across the inductor (vL) increases while the current decreases.

During the minimum input voltage, the switching cycle remains the same. However, since the input voltage is lower, the duty cycle must be adjusted to maintain a 5V output. By reducing the duty cycle, the average voltage across the inductor decreases, maintaining a stable output voltage.

The duty cycle is the ratio of the switch-on time to the total switching period. To calculate the respective duty cycles for the maximum and minimum input voltages, the relationship between the input and output voltages must be considered. In this case, the duty cycle required to maintain a 5V output is approximately 50% for both the maximum and minimum input voltages.

To fulfill the requirements, create classes in C++ for Franchise and League, extend with Player, Batsman, and Bowler classes, utilize polymorphism for desired output, and use file I/O for storing details.

In part a), we create the Franchise and League classes. The Franchise class will have a data member "name" of type string, and the League class will be composed of the Franchise class. Constructors and member functions will be implemented for both classes to handle their respective functionalities.

Moving on to part b), we extend the previous implementation to include the Player, Batsman, and Bowler classes. The Player class serves as the foundation, and the Batsman and Bowler classes are derived from it. Additional data members "country" of type string are added to the Batsman and Bowler classes.

To calculate batting and bowling averages, member functions such as "displayinfo()" will be implemented, which will utilize the given formulas: Batting Average = Runs Scored / Total Innings and Bowling Average = Total number of runs conceded / Total Overs.

Lastly, in part c), file I/O will be used to store the details of both parts a) and b). This will allow for data persistence and retrieval, ensuring that the information remains available even after the program execution ends.

We can find it using the Gram-Schmidt orthogonalization process. We start with the basis {f1, f2, f3}, and we apply the process to get:f4(t) = t³ - (3/5)t The four orthogonal signals are:f1(t) = 1f2(t) = t f3(t) = 3t² - 1f4(t) = t³ - (3/5)t.

(a) To show that the signals are orthogonal, we can use the following equation:∫^1-1f1(t) f2(t) dt

= 0.∫^1-1f2(t) f3(t) dt

= 0.∫^1-1f1(t) f3(t) dt

= 0

.Let's calculate the integrals:∫^1-11tdt

= 0 ∫^1-1(3t² - 1)tdt

= 0 ∫^1-1(3t² - 1)dt

= 0

Hence, the signals are orthogonal. (b) The signals f1, f2 and f3 form a basis for all polynomials of degree two or less. Let's see how. Let g(t) be a polynomial of degree two or less. We can write it in the form:g(t)

= at² + bt + c

We can then represent g(t) as a linear combination of f1, f2 and f3. Let's do it:g(t)

= (1/2a) ∫^1-1g(u)du + (b/2a) ∫^1-1ug(u)du + [(3/2)a - (c/2a)] ∫^1-1(3u²-1)g(u)du

= a[f1(t) - 1/3f3(t)] + b[1/2f2(t)] + c[2/3f3(t) - 1/3f1(t)]

Therefore, {f1, f2, f3} form a basis for all polynomials of degree two or less. (c) The next polynomial signal of degree 3 such that they are all orthogonal is f4(t). We can find it using the Gram-Schmidt orthogonalization process. We start with the basis {f1, f2, f3}, and we apply the process to get:f4(t)

= t³ - (3/5)t The four orthogonal signals are:f1(t)

= 1f2(t)

= t f3(t)

B = (σ3 - u)/(σ1 - u)

A = (σ1 - σ3)/(σ1 + σ3 - 2u)

B = (σ1 - σ2)/(σ1 - u)

Given data:

Cell pressure (σ1) = 850 kPa

Back pressure (u) = 250 kPa

Pore water pressure (u1) = 495 kPa

Pore water pressure (u2) = 620 kPa

Deviator stress (σ2) = 480 kPa

Let's calculate the values of the coefficients:

1. B:

B = (σ3 - u)/(σ1 - u)

We are given σ1 = 850 kPa and u = 250 kPa.

From the data, we can find σ3 using the equation: σ3 = σ1 - σ2

σ3 = 850 kPa - 480 kPa = 370 kPa

Now we can calculate B: B = (370 kPa - 250 kPa)/(850 kPa - 250 kPa) = 0.98

2. A:

A = (σ1 - σ3)/(σ1 + σ3 - 2u)

Using the values of σ1, σ3, and u calculated above, we have:

A = (850 kPa - 370 kPa)/(850 kPa + 370 kPa - 2*250 kPa) = 0.26

3. B:

B = (σ1 - σ2)/(σ1 - u)

Using the given values, we have:

The channel frequency response is β = Pm / 16000π.

Hc(ω) = 10^-3

The message signal PSD is

Sm(ω) = βrect(ω/2α),

with α = 8000π

The channel noise PSD is

Sn(ω) = 10^-8.

The required output SNR at the receiver is 30 dB.

The formula for calculating the received signal power is given by:

Prcv = Ptx |Hc(ω)|^2 Sm(ω)

The output SNR at the receiver is given by:

SNR = Prcv / Ps

Now,

Ps = Sn(ω),

we have

SNR = Prcv / Sn(ω)

=> Prcv = SNR * Sn(ω)

Given, SNR = 30 dB

=> SNR = 1000

Using the formula for received power and values for Hc(ω) and Sm(ω), we get:

Prcv = Ptx |Hc(ω)|^2 Sm(ω)

=> Prcv = Ptx * 10^-6 β

For the given SNR,

Prcv = SNR * Sn(ω)

= 1000 * 10^-8 = 10^-5

Using these values, we can equate both expressions for Prcv and solve for Ptx:

Prcv = Ptx * 10^-6 β

=> 10^-5 = Ptx * 10^-6 β

=> Ptx = 10 β

Therefore, the minimum transmitted power required is 10β mW.

To find β, we can use the formula for Sm(ω) and equate its integral over the entire signal band to the message power Pm.

Pm = ∫Sm(ω) dω

=> Pm = ∫β rect(ω/2α) dω

Using this formula, we get:

Pm = β * 2α

=> β = Pm / (2α)

=> β = (1/2) * (Pm / α)

=> β = (1/2) * (Pm / 8000π)

Given that the message PSD is

Sm(ω) = βrect(ω/2α),

with α = 8000π and

rectangular pulse width = 2α,

the message power is given by:

Pm = β * 2α

= β * 2 * 8000π

= 16000πβ

Substituting the value of β in terms of Pm, we get:

β = (1/2) * (Pm / 8000π)

=> β = (1/2) * (Pm / (16000π/2))

=> β = Pm / 16000π

Therefore, β = Pm / 16000π.

For the given transfer function of the LTI system is given as:S + 3 / S + 5Here, Numerator = S+3, Denominator = S+5The differential equation representation of the given transfer function is as follows:L{y(t)} = Y(s) = H(s)X(s)

The formula for the inverse Laplace transform is used to determine the time-domain response of the system.y(t) = L-1{Y(s)} = L-1{H(s)X(s)}Substitute the value of H(s) = (S + 3) / (S + 5)Therefore, y(t) = L-1{[(S+3)/(S+5)]X(s)}b. Output of the system y(t) for the input x(t):For the given input, x(t) = e^(-3t)u(t), we can calculate the output of the system y(t).Here, X(s) = 1 / (s + 3)Laplace transform is used to find Y(s).Y(s) = H(s)X(s) = (S + 3) / (S + 5) × (1 / (S + 3))= 1 / (S + 5)

Quadrature-phase-shift keying (QPSK) is a digital modulation technique that uses four points on a signal constellation. QPSK modulates two separate signals that are quadrature (or in-phase) with each other.

In other words, the two signals are orthogonal to each other and carry separate data streams. In QPSK modulation, each pair of bits is mapped to a unique phase shift of the carrier signal, resulting in four possible phase states.

These states are 45, 135, 225, and 315 degrees, which correspond to the four points of the constellation diagram.
The signal constellation diagram consists of four points on a square grid, with each point corresponding to a unique pair of bits.

The two signals are represented by the real and imaginary axes, and each point on the diagram corresponds to a specific phase shift of the carrier signal. When a signal is transmitted using QPSK modulation, it is modulated onto the carrier signal and transmitted as a sequence of phase shifts.

The receiver demodulates the signal by detecting the phase shift of each received symbol and mapping it back to the corresponding pair of bits.

The exact numerical values and calculations depend on the specific dimensions and properties of the column, which are not provided in the question.

The buckling load of a pin-ended column can be determined using the finite difference method with four subdivisions of equal length. By denoting the nodal points as 0, 1, 2, and 3, with 0 and 3 located at the ends, and locating the origin of coordinates at the stationary end, we can proceed with the calculations.

To apply the finite difference method, we start by discretizing the column into four segments. Let's assume the length of the column is denoted by L, and each subdivision has a length of L/4.

Next, we can define the deflection of the column at each nodal point. Let's denote the deflection at node i as δ(i), where i ranges from 0 to 3.

Considering the equilibrium of forces, we can write the difference equation for the deflection at each nodal point. Using the finite difference approximation, we have:

δ(i-1) - 2δ(i) + δ(i+1) = 0

This equation represents the balance of moments at each node, assuming a constant cross-section and neglecting the effect of axial load.

Applying the boundary conditions, we have:

δ(0) = 0 (stationary end)

δ(3) = 0 (pin-ended end)

We can solve the system of equations formed by these difference equations and boundary conditions to determine the deflection at each nodal point. The buckling load of the column can be found by examining the critical load at which the deflection becomes significant or when the column loses stability.

It's important to note that the exact numerical values and calculations depend on the specific dimensions and properties of the column, which are not provided in the question. The above explanation outlines the general approach to determine the buckling load using the finite difference method for a pin-ended column with equal subdivisions and a constant cross-section.

It is required to prove that if Y(t) = X(t) * H(t) then Y(2t) = X(2t) + N(2t).Y(t) can be written as: Y(t) = X(t) * H(t).And, we know that Y(2t) = X(2t) + N(2t) Let's put t = 2t / 2 = t in Y(t)Y(t) = X(t) * H(t)Y(2t/2) = X(2t/2) + N(2t/2)Y(2t) = X(t) * H(t) + N(t). Multiplying both sides by H(t)Y(2t) * H(t) = X(t) * H(t) * H(t) + N(t) * H(t)Y(2t) * H(t) = X(t) + N(t) * H(t)So, Y(2t) = X(t) + N(t) * H(t).

Let's suppose that Y(t) = X(t) * H(t).

We are supposed to prove that if this is true, then

Y(2t) = X(2t) + N(2t).

To prove this, we need to start with Y(t), and see how we can transform it into Y(2t).

We know that Y(2t) = X(2t) + N(2t).

Let's replace 2t with 2t/2, so we get:

Y(2t/2) = X(2t/2) + N(2t/2)

Simplifying this, we get:

Y(t) = X(t) + N(t) * H(t)

Multiplying both sides by H(t), we get:

Y(t) * H(t) = X(t) * H(t) + N(t) * H(t)

Finally, we can replace t with 2t to get:

Y(2t) * H(2t) = X(2t) * H(2t) + N(2t) * H(2t)

Dividing both sides by H(2t), we get:

Y(2t) = X(2t) + N(2t)

Therefore, we have proven that if Y(t) = X(t) * H(t), then Y(2t) = X(2t) + N(2t).

Thus, we can conclude that if Y(t) = X(t) * H(t), then Y(2t) = X(2t) + N(2t).

This is the difference between synchronous and asynchronous counter. Also, a synchronous counter which can count from 0 to 9 clock pulses and reset at the 10th pulse using JK flip flops is constructed using the above-provided steps with appropriate waveforms.

Synchronous Counter:

A synchronous counter is a counter in which the flip-flops are triggered with the same clock pulse. The flip-flops are used in conjunction with the logic gates to achieve synchronous counter operation. Since each flip-flop change happens at the same time, it is termed as a synchronous counter.

Asynchronous Counter:

An asynchronous counter is a counter in which the flip-flops are triggered by the output pulse of the preceding flip-flop. The output pulses of the preceding flip-flop are not produced at the same time as the clock pulse.

As a result, it is also known as a ripple counter.Asynchronous counters can be made using J-K flip-flops. A J-K flip-flop will change its output on every clock cycle if the J and K inputs are tied together to create a toggle flip-flop. As a result, a four-stage ripple counter that counts from 0 to 15, as shown below, can be created:

To design a synchronous counter which can count from 0 to 9 clock pulses and reset at the 10th pulse using JK flip flops, we follow these steps:

Step 1: Construct the Truth Table:The truth table for the synchronous counter is constructed as follows:

Step 2: Develop the Karnaugh Map:Using the truth table, K-maps for the next state and outputs of the JK flip-flops can be developed.

Step 3: Design of Circuit:

With the help of the K-maps, the circuit for the synchronous counter can be designed using JK flip-flops.

The circuit diagram for the synchronous counter which can count from 0 to 9 clock pulses and reset at the 10th pulse using JK flip-flops is shown below:

In the above figure, A, B, C and D are the four flip-flops.Each flip-flop has a common clock pulse (CP).As each flip-flop operates on the positive edge of a clock, the inputs of the flip-flops are given from the outputs of the flip-flop on its left-hand side.

The counter will start from zero when the system is powered on. At each positive clock edge, the count value will be incremented by one. If the count reaches 9, the next count value will be zero. If the count reaches 10, the output Q of the flip-flop in the 4th stage will become 1, resetting the counter to 0 at the next clock pulse.

Appropriate waveforms for the synchronous counter are given below: Therefore, this is the difference between synchronous and asynchronous counter. Also, a synchronous counter which can count from 0 to 9 clock pulses and reset at the 10th pulse using JK flip flops is constructed using the above-provided steps with appropriate waveforms.

The program utilizes an abstract class called `Stringsort` with a method `checkString` to sort the string arrays by ASCII order and length, implementing a custom sorting algorithm, ensuring no libraries are used.

The given program requires sorting string arrays based on vocabulary using ASCII order and length as the sorting priority. The program must not use any libraries.

To solve this, an abstract class named `Stringsort` is defined with a method `checkString` that takes an array of strings as input and returns a sorted array of strings. The sorting is performed in two steps:

1. The strings are sorted based on ASCII order using a custom sorting algorithm.

2. Strings with the same ASCII value are then sorted based on their length.

The algorithm compares each string element with the next one in the array and swaps them if they are in the wrong order. This process is repeated until the array is sorted.

This implementation uses the `compareTo` method to compare strings based on ASCII order and the `length` method to compare strings based on length. The sorting is performed using a bubble sort algorithm.

The output for the given example input ["Once", "a", "upon", "time"] will be ["Once", "a", "time", "upon"].
