Consider a causal system given by the system function

(a) Compute and plot magnitude and phase responses of the system.

(b) Determine the minimum-phase system Hmin(z) corresponding to H(z) and plot its magnitude and phase responses.

(c) Determine the equalizer system Heq(z) corresponding to H(z) and choose gain G so that the overall system |H(z)Heq(z)| = 1. Plot its magnitude and phase responses.
