Question: Let h[n] and H(z) denote the impulse response and system function of a stable all-pass LTI system. Let h i [n] denote the impulse response

Let h[n] and H(z) denote the impulse response and system function of a stable all-pass LTI system. Let h_i[n] denote the impulse response of the (stable) LTI inverse system. Assume that h[n] is real. Show that h_i[n] = h[– n].
