13.6 PROPERTIES OF FOURIER SERIES AND SOME EXAMPLES
Let us take some examples of Fourier series and develop the important properties of this
series through them. The waveforms used in the examples that follow are very important
signal waveforms that appear frequently in Electrical and Electronic Engineering
applications and are not just some functions used to illustrate Fourier series. The waveforms
appearing in the examples are important in their own right.
The first property of Fourier series is almost self-evident. It is the property of
linearity. It states that if v
1
(t) and v
2
(t) are two periodic waveforms with the same period T
and v
3
(t) ...
