Q3. Consider a system whose z-transfer function is given below, where the parameters K. 1, and r, are all real numbers H(z) = K 22-25, cos(1)z+r, 2 a) What are the conditions, if any, on the parameters for the system to be stable? (15 marks) b) Changing the Z-transfer function to the following expression (where m is an integer) does it affect the system stability? Explain (5 marks) Kz H(z) = z"[ 22 -27, -cos (22, )2+r]
