5. (4 pts) (Programming assignment.) (a) Write a simple code (preferably in Python) that uses discrete convolution to find the response to the input r[n] of an LTI system with the impulse response h[n (see figure below. Plot the response. Submit your code, print out and submit the response 101 2 345 hln] 0 1 2 3 45678 9 10 12 14 16 (b) Plot the magnitude and phase of the frequency response of the LTI system given by 0.008-0.033e-jw + 0.05e-2jw-0.033e-3jw + 0.008e-qu H (ej") = Hint: "numpy.convolve" and "scipy.signal.freqz" are Python functions useful for (a) and (b) respectively
