Question: 5 consider the io relation where xn is the input...

Question details

5. Consider the I/O relation where x[n is the input and y[n] is the output. Recursion is implemented in a causal manner. (a) Find the frequency response and plot H(e). (b) Is this system stable? Prove your answer. (c) Will this system be stable if the recursion is implemented in an anti-causal man nCr (d) Let the input x[n] be a white, zero-mean random process with variance 1. Will yn be a wide sense stationary random process? Determine the spectrum of y[n i.e., Sy(ei)
