Question details

PLEASE SOLVE THE PROBLEM VERY NEATLY! PLEASE SHOW ALL THE STEPS OF THE PROBLEM! PLEASE EXPLAIN IN GREAT DETAIL! PLEASE USE MATLAB TO SOLVE FOR PART E! PLEASE SOLVE THE PROBLEM IN GREAT DETAIL! PLEASE PROVIDE ME WITH THE MATLAB CODE! PLEASE SOLVE PARTS A-E!Assume that two LTI systems, whose impulse responses are hi[n]-o[n] + 0.25 δ[n-2]-δ[n-j and ha[n]- (0.5)u[n], are connected in cascade. a. Using the z-transform approach, show that the impulse response, h[n] of the overall system is 3. (25 points) given by h[n-δ[n]-0.5 δ[n-1] b. Determine the difference equation representation of the overall system. c. Is the system causal? Is it stable? Explain briefly to receive full credit. d. Determine the frequency response, H), of the overall system. e, Plot the frequency response (both magnitude and phase) over 0 ω π using MATLAB.
