8.23. Consider the real finite-length sequence x[n] shown in Figure P8.23. x[n] 3 11 0 1 2 3 " Figure P8.23 (a) Sketch the finite-length sequence y[n] whose six-point DFT is Y [k] = W* x [k], where X [k] is the six-point DFT of x[n]. (b) Sketch the finite-length sequence w[n] whose six-point DFT is W[k] = Im{X [k]). (c) Sketch the finite-length sequence q[n) whose three-point DFT is Q[k] = X (2k + 1], k=0,1,2.
