Consider the two systems shown in Figure P4.44.

where Q(·) represents a quantizer which is the same in both systems. For any given G(z), can H(z) always be specified so that the two systems are equivalent (i.e., yA [n] = yB [n] when xA [n] = xB [n]) for any arbitrary quantizer Q(·)? If so, specify H(z). If not, clearly explain your reasoning.
