(a) Plot the single-sided and double-sided amplitude and phase spectra of the square wave shown in Figure 2.35(a).

(b) Obtain an expression relating the complex exponential Fourier series coefficients of the triangular waveform shown in Figure 2.35(b) and those of X_a (t) shown in Figure 2.35(b).

Plot the double-sided amplitude and phase spectra for x_b(t).
