The periodic pulse train in Figure P13–20 is applied to the RL circuit shown in the figure.

(a) Use the results in text Figure 13–4 to find the Fourier coefficients of the input for VA ¼ 10V, T0 ¼ p ms; and T ¼

T0=4:

(b) Find the first four nonzero terms in the Fourier series of vo(t) for R ¼ 400V, and L ¼ 100 mH.
