Figure P1.22 1.22. A discrete-time signal is shown in Figure P1.22. Sketch and label carefully each of the following signals: (a) \( x[n-4] \) (b) \( x[3-n] \) (c) \( x[3 n] \) (d) \( x[3 n+1] \) (e) \( x[n] u[3-n] \) (f) \( x[n-2] \delta[n-2] \) (g) \( \frac{1}{2} x[n]+\frac{1}{2}(-1)^{n} x[n] \) (h) \( x\left[(n-1)^{2}\right] \)
