Z Problem 1 Consider a discrete-time system whose system function (transfer function of the system) is given by 1 H(2) 1 ſz-1 +3z-2 -1 (a) Sketch the zero-pole plot of the system using MATLAB. Hint: Use zplane MATLAB function. (b) Find the values of these zeros and poles using two methods? Hint: There are several methods by which zeros and poles can be computed, one of them is to use tf2zp MATLAB function. Make sure to get all the zeros obtained in part (a). Problem 2 (a) The zeros and poles of the system function, H(2), of a discrete-time system are as follows: zeros: z = 1, z = 2 and poles: 2 = 1, z = -1, z = -1. Use MATLAB to find an expression for H(2). Hint: Use zp2tf MATLAB function assuming the gain is equal to 1. (b) Use MATLAB to find an expression for H (2) if the zeros and poles are as follows: zeros: z = 1 and poles: z = -1 + j2, z= -1 - j2. Assume the gain = 2.
