Quelltext der Seite Pulse width modulation

modulation of the symmetry of a square [[waveform]]. this generates a lot more higher harmonics spectra / overtones.

nice for fatten or thicken up sounds like pads / strings and fat basses, especially introduced on smaller synthesizers to get a bigger sound our of one [[oscillator]].

short: PWM

the Pulse Width ([[PW]]) is fixed while [[PWM]] is the modulation of the symmetry.
