white noise

Definitions

Economics

• noun a series of observations made over a period of time which are random and completely independent

Electronics

• Noise whose sound energy or intensity per hertz is the same throughout a given frequency interval, such as the audible spectrum. The frequency response of such noise is flat, while that of pink noise drops off with frequency. Specifically, white noise passed through a filter with a 3 dB/octave roll off results in pink noise. White noise is analogous to white light, as it contains equal amounts of all audible frequencies. An example is thermal noise.
