Question

Determine the z-domain transfer function for each of the following LTI systems. The impulse response for these expressions is denoted by h[n], the input signal by x[n], and the output signal by y[n]. Provide your response as the ratio of two finite-order z polynomials or as a z polynomial of finite order. Assume that the input signal starts at n = 0 or later in every scenario. For n < 0, further suppose that y[n] = 0. Indicate if the system is IIR or FIR.
