(iii) (6 pts.) If - NNW DU 2 - 3 - 2 3 5 explain how the vector c can be obtained using DFTs (as opposed to a conventional solution of a 6 x 6 system of equations). Implement this solution in MATLAB to obtain C. (iv) (5 pts.) Let x and y be time domain vectors of length NV such that for every n =0 , ..., N-1, 1 [ ] = y[n] If X and Y are the respective DFTs, determine the circular convolution vector X Y
