13.9 ANALYSIS OF PERIODIC STEADY-STATE USING FOURIER SERIES

The first step of analysis is the determination of Fourier series of the periodic input waveform in exponential format or trigonometric format. The second step is the determination of frequency response function connecting the required output variable to the input variable. The third step is the determination of steady-state response for each term in the Fourier series of input waveform. The fourth step is to combine all these steady-state response components and to obtain the instantaneous waveform of output after deciding the number of terms to be retained in the truncated Fourier series of the output waveform.

This procedure is illustrated through examples that follow.
