Chapter 10, Problem 10.44(choose chapter or problem)
Let x[n] be a discrete-time signal with z-transform X(z). For each of the following signals, determine the z-transform in terms of X(z): (a) Llx[n], where Ll is the first-difference operator defined by Llx[n] = x[n] - x[n- 1] (b) XI [n] = { x[n/2], 0, (c) x 1 [n] = x[2n]
