Webof the white-noise signal is Gaussian—like the independent steps in Brownian motion. However, any zero-mean amplitude distribution can define a non-Gaussian white-noise process (signal) as long as the values of the signal satisfy the aforementioned condition of statistical independence (see Section 2.2.4 for examples of non-Gaussian white ... WebWhite Noise, by definition, works by defining parameters in which data is ensured to be random, unrelated, and have zero mean.
