Noise generator
White noise generator
This component generates a White noise. The White noise is a random signal (or process) with a flat
power spectral density. In other words, the signal contains equal power within a fixed bandwidth at
any center frequency.
An infinite-bandwidth, white noise signal is purely a theoretical construction. By having power at all
frequencies, the total power of such a signal is infinite and therefore impossible to generate. In
practice, however, a signal can be "white" with a flat spectrum over a defined frequency band.
As example, it can be used to set up the equalization for a concert or other performance in a venue, a
short burst of white or pink noise is sent through the PA system and monitored from various points
in the venue so that the engineer can tell if the acoustics of the building naturally boost or cut any
frequencies. The engineer can then adjust the overall EQ to ensure a balanced mix.
