Pink Noise Generator

Sine 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.
