This raises two questions – (i) Why did the Electrical Power Industry prefer sinu-
soidal waveform to any other waveform? (ii) Why does Electronics and Communications
Engineering concern itself with sinusoidal analysis though a single-frequency sinusoid is
hardly ever employed in a communication system?
These two questions are answered first in this chapter. Subsequently, the concepts of

sinusoidal waveforms as well as for other ...
