Question 3: (5pts) Suppose a continuous-time signal $x_c(t)$ has the Fourier transform shown in the figure below where $(\Omega_2 - \Omega_1) = \Delta \Omega$. This signal is sampled to produce the sequence $x[n]=x_c(nT)$. a. Sketch the Fourier transform $X(e^{j\omega})$ of the sequence $x[n]$ for $T = \frac{\pi}{\Omega_2}$. b. What is the lowest sampling frequency that can be used without incurring any aliasing (so that $x_c(t)$ can be recovered from $x[n]$)? c. Draw the block diagram of a system that can be used to recover $x_c(t)$ from $x[n]$ if the sampling rate is greater than or equal to the rate determined in Part (b). Hint, first convert the signal to a sequence then apply a filter. $X_c(j\Omega)$ 0 $\Omega_1$ $\Omega_2$ $\Omega$ $\Delta \Omega$

Q4. Write a c program to simulate the different CPU scheduling algorithms. Four scheduling algorithms should be implemented in the program: [25 pts] 1. First In First Out (FIFO) 2. Shortest Job First (SJF) 3. Shortest Remaining Time First (SRTF) 4. Round Robin (RR) The program should accept input for n processes (n>4), where each process has: ● Process ID: A unique identifier for the process. ● Arrival Time: The time at which the process arrives in the ready queue. ● Burst Time: The total time required by the process for execution. ● Time Quantum (TQ): The value of TQ should only be used in RR. For each scheduling algorithm, the program should: ● Calculate and display the order of execution of processes. ● Calculate and display the scheduling policy's Average Response Time and Average Turnaround Time.

A force is applied over a period of 2 seconds on the rope towards B and away from A, the speed of object A is reduced to 2 m/s as a result. a) Determine the speed of object B (m/s) at the end of the 2-second interval. v = 3 m/s A m = 30 Kg v = 3 m/s B m = 70 Kg b) What is the rope tension (N) during the 2-second interval? Answers a) $v_B = 3.43 \text{ m/s}$ b) $F = -15 \text{ N}$
