Question: Let h min [n] denote a minimum-phase sequence with z-transform H min (z). If h[n] is a causal non-minimum-phase sequence whose Fourier transform magnitude is

Let h_min[n] denote a minimum-phase sequence with z-transform H_min(z). If h[n] is a causal non-minimum-phase sequence whose Fourier transform magnitude is equal to |H_min(e^j?)|,

Show that?

|h[0]| min[0]|.

?(Use the initial-value theorem together with Eq. (5.103).)

H(2) = Hmin(2)Hap(2). (5.103)
