A system with input and output signals X(n) and Y(n), respectively, is given below: Y(n) = 165Y(n-1) - 0.9Y(n-2) + X(n) (a) Find its system function H(z) (b) Find poles, zeros, and the region of convergence (ROC) of H(z) for this causal system. Is it also stable? (c) Find the impulse response h(n) of this filter. (d) Draw a block diagram or signal flow graph representation of this filter with the minimum number of delay elements.
