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:
“It is as real
as splinters stuck in your ear. The noise we steal
is half a bell. And outside cars whisk by on the suburban street
and are there and are true.
What else is this, this intricate shape of air?
calling me, calling you.”
—Anne Sexton (1928–1974)
