Answer:
A complex wave is a wave made up of a series of sine waves; it is therefore more complex than a single pure sine wave. This series of sine waves always contains a wave called the "FUNDAMENTAL", that has the same FREQUENCY (repetition rate) as the COMPLEX WAVE being created.
Examples for complex wave:
<em>• The Square wave
</em>
<em>• The Triangular wave
</em>
<em>• The Saw-tooth wave</em>
