Two signals s(n) and v(n) are related through the following difference equations.

Design the block diagram realization of:

(a) The system that generates s(n) when excited by v(n).

(b) The system that generates v(n) when excited by s(n).

(c) What is the impulse response of the cascade interconnection of systems in parts (a) and (b)?
