A sawtooth wave has peak-to-peak amplitude of 5 V and a fundamental frequency of 100 Hz. Use the results in Figure 13-4 to write an expression for the first four nonzero terms in the Fourier series and plot the amplitude spectrum of the signal. Use MATLAB to plot two periods of the original signal and an estimate for the signal using the first four nonzero terms in the Fourier series. Comment on the differences between the two waveforms.
