The periodic sawtooth wave in Figure P13-20 drives the OP AMP circuit shown in the figure.
(a) Use the results in Figure 13-4 in the text to find the Fourier coefficients of the input for \(V_{\mathrm{A}}=3 \mathrm{~V}\) and \(T_{\mathrm{o}}=4 \pi\) \(\mathrm{ms}\).
(b) Find the first four nonzero terms in the Fourier series of \(v_{\mathrm{O}}(\mathrm{t})\).
(c) Simulate the circuit using Multisim. Use the triangular source and make the fall time very short ( \(0.1 \mathrm{ps})\). Plot three cycles of the output. The voltage limit for the OP AMP is \(V\) \(\mathrm{CC}= \pm 15 \mathrm{~V}\). Explain why the plot looks like it does.
