A causal discrete-time LTI system is described by y [n] - fr [n - 1] + i y [n - 2] = x [n] where  x [n]  and y [n] are the input and output  of  the system, respectively.

(a) Determine the frequency response H(fl) of  the system.

(b) Find the impulse response h[n] of the system.

(c) Find y [n] if x [n] = q)nu[n].
