random noise random noise[′ran·dəm ′nȯiz] (mathematics) A form of random stochastic process arising in control theory. (physics) Noise characterized by a large number of overlapping transient disturbances occurring at random, such as thermal noise and shot noise. Also known as fluctuation noise. random noiseA type of noise comprised of transient disturbances which occur at random times; its instantaneous magnitudes are specified only by probability distribution functions which give the fraction of the total time that the magnitude lies within a specified range. |
