(6 +036-28 43") answer the 1-42 • A discrete-time causal LTI system has the system function H(-) = 1 1 -0.642-2) following related questions. a) Plot the pole-zero diagram of H(-). Indicate the ROC. b) Find the inverse system function, H (2), which is known to be stable. Indicate the ROC. c) Express H(-) as H(-) = H mp(z)Hap(2), where h mp (-) is a minimum-phase system and Hap(-) is an all-pass system. (Hint: All the poles and zeros lie in the unit circle in a minimum-phase system. The poles and zeros occur in conjugate reciprocal pairs in an all-pass system.) d) Sketch the magnitude-spectrum of the minimum-phase system, Hmp
