The term uncorrelated noise refers to a noise source being uncorrelated to a signal or another noise source.[1] White noise in particular, due to its randomness, is uncorrelated to any other signal and is also serially uncorrelated (i.e., later values of it have no correlation to earlier values). Thus, "uncorrelated noise" is sometimes imprecisely[citation needed] used synonymously with "white noise". However, in general, noise sources can have any noise spectrum and may or may not be correlated with each other (in practice different noise sources are usually uncorrelated[2]). This situation is sometimes described as "uncorrelated colored noise".[3]
