The periodic pulse train in Figure P13-19. is applied to the \(R L\) circuit shown in the figure.
(a) Use the results in text Figure 13-4 to find the Fourier coefficients of the input for \(V_{\mathrm{A}}=12 \mathrm{~V}, T_{\mathrm{O}}=2 \pi \mathrm{ms}\), and \(T=\)

\(T_{\mathrm{o}} / 4\).
(b) Find the first four nonzero terms in the Fourier series of \(v_{\mathrm{o}}(t)\) for \(R=470 \Omega\) and \(L=220 \mathrm{mH}\).
