White Noise Generator

Purpose

Generates a white noise test signal. White noise contains equal amounts of energy at each frequency. When viewed on a constant bandwidth analyzer such as an FFT analyzer it will appear flat. However when viewed on a constant percentage bandwidth analyzer such as all the common Real Time Analyzers, it will appear to increase in level with increasing frequency at a rate of 3 dB per octave. For use with RTA’s, use the pink noise generator instead, which will appear flat on them.

Controls

Level

Sets the RMS level of the noise generated. The peak level for white noise is 4.77dB greater than its RMS level.

Mute

Mutes the output of the generator.
