INTRODUCTION
This chapter deals with the determination of forced response component in the output of dynamic circuits when they are excited by periodic input waveforms. The problem of expressing a periodic waveform as a sum of pure sinusoidal components is addressed first. Subsequently, the use of frequency response data to solve for forced response when the forcing function is such a sum of sinusoidal components will be dealt with.
Fourier series expansion deals with periodic waveforms. It resolves a periodic waveform into pure sinusoidal components. Equivalently, it expands the periodic waveform as a linear combination of infinitely many harmonically related sinusoidal waveforms. Two sinusoids are harmonically related if their frequencies are ...
