A '''pulse wave''' or '''pulse train''' is a kind of [[non-sinusoidal]] [[waveform]] that is similar to a [[square wave]], but does not have the symmetrical shape associated with a perfect square wave. It is a term common to [[Analog synthesizer|synthesizer]] programming, and is a typical waveform available on many synths. The exact shape of the wave is determined by the [[duty cycle]] of the [[oscillator]].
The pulse wave is also known as the rectangular wave, the [[Periodic function|periodic]] version of the [[rectangular function]].
