Transcribed Image Text:

The 20-point signal r(n) is given by x(n) = sin 2n 0<n<N-1 where N = 20. (a) Roughly sketch the signal for 0 <n< 19. Do not explicitly calculate the values. (b) Find the DFT coefficients of the signal. That means, find X(k) for 0 < k< 19. Show the derivation of your answer. You should not use direct computation of the DFT.
