Consider the system

(a) Draw all possible realizations of the system.

(b) Suppose that we implement the filter with fixed-point sign-and-magnitude fractional arithmetic using (b + 1) bits (one bit is used for the sign). Each resulting product is rounded into b bits. Determine the variance of the rounded-off noise created by the multipliers al the output of each one of the realizations in part(a).
