White noise refers to a statistical model for signals and signal sources, rather than to any specific signal.The term is also used for a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean and finite variance. Depending on the context, one may also require that the samples be independent and have the same probability distribution.
