13–52 Fourier Series from a Bode Plot The transfer function of a linear circuit has the straightline gain and phase Bode plots in Figure P13–52. The first four terms in the Fourier series of a periodic input v1(t) to the circuit are

Estimate the amplitudes and phase angles of the first four terms in the Fourier series of the steady-state output v2(t).

vi(t)=42cos (751)+14cos(2251) + 8.4cos(3751)+6cos(5251) V
