5+1 Exercise 4: In the following transfer function (1). A(s) = 1. (2). B(s) = (3). C(s) = $ (4). D(s) = S2+2s+100 (a). Define the transfer function in MATLAB using any method you prefer, find the poles and zeros of the system. (b). Use MATLAB commands to simulate the responses of each system when inputs are Sl(step input with amplitude of 1.5), S2 (unit sine wave of 10Hz), and S3 (unit square wave of 2Hz). (c) Discuss the results you observed
