Triangle wave
Overview
 
A triangle wave is a non-sinusoidal waveform
Non-sinusoidal waveform
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...
