Question: Exercise 4 The length-3 sequence go = -3, a = 2, az = 1 is convolved with a second sequence (bm] of length 5. (a)

Exercise 4 The length-3 sequence go = -3, a = 2, az = 1 is convolved with a second sequence (bm] of length 5. (a) Write down this linear operation as a matrix multiplication involving a matrix A, a vector D R5, and a result vector &. (b) Use MATLAB to multiply your matrix by the vector b = (1, 0, 0,2,2) and compare the result with that of using the conv function. (c) Use the MATLAB facilities for solving systems of linear equations to undo the above convolution step.
