and well explained answers. I. Filter analysis Consider the filter T yn+21yn1=xnxn4 and denote by hn=T(n) its impulse response. 1. Is the filter conditional? 2. Compute H(z)=Z[hn](z). 3. Compute the ROC of H(z). 4. Is the filter stable? 5. Is the filter FIR or IIR. 6. Explain why h^(u) the FT of hn exists. Compute h^(u). 7. Compute h^(u) at u=0,41,21. Is the filter high-pass, low-pass or neither of the two? 8. Find yn for n5 for the input xn={2n10n0n
