Gaussian noise is statistical noise that has its probability density function equal to that of the normal distribution, which is also known as the Gaussian distribution. In other words, the values that the noise can take on are Gaussian-distributed. A special case is white Gaussian noise, in which the values at any pairs of times are statistically independent (and uncorrelated). In applications, Gaussian noise is most commonly used as additive white noise to yield additive white Gaussian noise.

Famous quotes containing the word noise:
“Your next-door neighbour ... is not a man; he is an environment. He is the barking of a dog; he is the noise of a pianola; he is a dispute about a party wall; he is drains that are worse than yours, or roses that are better than yours.”
—Gilbert Keith Chesterton (1874–1936)
