Consider the waveforms x_c(t) and X_d(t) in Figure P4.10. Let the difference of these signals be x_s(t). Then x_s(t) is the same waveform of Example 4.2, except for the average value. Show that the Fourier coefficients of x_s(t) are equal to those of x(t) in Example 4.2, except for the average value.
