Non-sinusoidal waveforms are
waveforms that are not pure
sine waves. They are usually derived from simple math functions. While a pure sine consists of a single frequency, non-sinusoidal waveforms can be described as containing multiple sine waves of different frequencies. These "component" sine waves will be whole number multiples of a
fundamental or "lowest" frequency. The frequency and amplitude of each component can be found using a mathematical technique known as
Fourier analysis.
