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:
“We need to find God, and he cannot be found in noise and restlessness. God is the friend of silence. See how nature—trees, flowers, grass—grows in silence; see the stars, the moon and the sun, how they move in silence.... We need silence to be able to touch souls.”
—Mother Teresa (b. 1910)
