The two-sided transfer function of a linear time-invariant (LTI) system, H(z), is described as H(z) = (1-2z-¹)(1+2¹) (1-0.2z-¹)(1-0.4z-¹) (a) Classify whether H(z) is maximum, minimum or mixed phase function. Justify your choice. [2 marks] (b) Characterize H(z) as a minimum phase function, Hmin (2), in cascade with an all-pass function, Hap (2).
