A discrete-time signal x[n] is shown in Fig. Sketch and label each of the following signals. a) x[n]u[3 - n] b) x[n]u[n - 3] c) x[n]{u[n + 2] - u[n]} d) x[n]δ[n - 2] Express the signals shown in Fig: in terms of unit step functions.

A discrete-time signal x(n) is defined as x(n) = {1 + n/3, -3 <= n <= -1; 1, 0 <= n <= 3; 0, elsewhere} a. Determine its values and sketch the signal x(n). b. Sketch the signals that result if we: 1. First fold x(n) and then delay the resulting signal by four samples. 2. First delay x(n) by four samples and then fold the resulting signal. c. Sketch the signal x(-n + 4). d. Compare the results in parts (b) and (c) and derive a rule for obtaining the signal x(-n + k) from x(n). e. Can you express the signal x(n) in terms of signals delta(n) and u(n)?
