Let x 1 [n] be a sequence obtained by expanding the sequence x[n] = (1/4) n u[n]
Question:
Let x1[n] be a sequence obtained by expanding the sequence x[n] = (1/4)n u[n] by a factor of 4; i.e.,
Find and sketch a six-point sequence q[n] whose six-point DFT Q[k] satisfies the two constraints.
?Q[0] = X1(1),
Q[3] = X1(? 1),
?where X1(z) represents the z-transform of X1[n].
