(a) Draw the flow graph of a direct-form nonrecursive implementation of the system.

(b) Show that the corresponding system function can be expressed as

(c) Draw the flow graph of an implementation of H(z), as expressed in part(b), corresponding to a cascade of an FIR system (numerator) with an IIR system (denominator).

(d) Is the implementation in part (c) recursive or nonrecursive? Is the over all system FIR or IIR?

(i) the most storage (delay elements)?

(ii) the most arithmetic (multiplications and additions per outputsample)?
