The periodic sawtooth wave in Figure P13–22 above drives the OP AMP 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 8V and T0 ¼ 20p ms

(b) Find the first four nonzero terms in the Fourier series of i(t) for R1 ¼ 100 kV, R2 ¼ 50 kV, and C ¼ 0.4mF.

(c) Find the first four nonzero terms in the Fourier series of vO(t) with the same element values as in part (b).
