Question
\text { Problem 3. For a system described by } y[n]=x[n] * h[n], \text { let } x[n]=(3)^{-n} u[n] \text { and } h[n]=\left(\frac{4}{5}\right)^{n} u[n]: a. Compute y[n] analytically. Plot y[n] in MATLAB for –5 <= n <= 15. b. Compute y[n] = x[n] * h[n] using the conv command in MATLAB. Plot y[n] in MATLAB for -5 <= n <=
