Pink noise with a continuous frequency spectrum with equal power per constant percentage bandwidth. Also see Pink Noise or White Noise.
Any kind of hiss-like noise produced by special noise generators. Similar noise can also be heard when a TV or radio tuner is tuned to a channel that has no station transmitting. See also Pink noise; White noise.
Random noise represents a nondeterministic fluctuation in the output of an ADC, described by its frequency spectrum and its amplitude statistical properties.
