13.14 PROBLEMS

1. One cycle of a waveform v(t) is shown in Fig. 13.14-1. It is a symmetrically clipped sinusoid. (i) Obtain a time-shifted version of this waveform such that the resulting waveform has odd symmetry. (ii) Find the trigonometric Fourier series of the shifted version and thereby obtain the discrete Fourier spectrum for v(t).
