The sawtooth waveform in Fig. P7.31 can be expressed in the form of a Fourier series as

(a) Determine the Fourier series coefficients

(b) Use an N -point subroutine to generate samples of this signal in the time domain using the first six terms of the expansion for N = 64 and N = 128. Plot the signal x(t) and the samples generated, and comment on the results.
