The Model 31 Pink Noise Generator logic module with Octal plug-in.
Pink noise or 1/ƒ noise ( flicker noise) is a signal with a frequency spectrum such that the power spectral density (energy or power per Hz) is inversely proportional to the frequency. The name arises from the pink appearance of visible light with this power spectrum.
A pink noise source is sometimes included on analog synthesizers as a useful audio sound source for further processing, and as a source of random control voltages for controlling other parts of the synthesizer.
