Before starting, it is necessary to discuss some fundamentals that are important in
understanding analogue and digital transmission. The first area that is discussed is
what is meant by frequency. Also the make-up of complex waveforms such as
square and sawtooth waveforms is described. In order to understand a complex
waveform a knowledge of harmonic frequencies is necessary, and this is
explained.
