power-additive noise
11Noise — This article is about noise as an unwanted phenomenon. For other uses, see Noise (disambiguation). NASA researchers at Glenn Research Center conducting tests on aircraft engine noise in 1967 In common use, the word noise means any unwanted …
12Noise floor — This article is about physics term. For the Bright Eyes album, see Noise Floor (Rarities: 1998 2005). In signal theory, the noise floor is the measure of the signal created from the sum of all the noise sources and unwanted signals within a… …
13Noise (video) — For other uses, see Noise (disambiguation). On an empty channel, an analog TV receiver shows a snowy noise pattern. A similar pattern is shown if on a digital channel when not using a DTV converter box …
14Signal-to-noise ratio — For signal to noise ratio in statistics, see Cohen s d. Signal to noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined… …
15Colors of noise — White Pink Red (Brownian) Grey While noise is by definition derived from a random signal, it can have different characteristic statistical properties corresponding to different mappings from a source of randomness to the concrete noise. Spectral… …
16Johnson–Nyquist noise — (thermal noise, Johnson noise, or Nyquist noise) is the electronic noise generated by the thermal agitation of the charge carriers (usually the electrons) inside an electrical conductor at equilibrium, which happens regardless of any applied… …
17List of noise topics — This is a list of noise topics. Contents 1 Engineering and physics 2 Environmental 3 Noise reduction 4 Music …
18Electronic noise — is an unwanted signal characteristic of all electronic circuits. Depending on the circuit, the noise put out by electronic devices can vary greatly. This noise comes from many different electronic effects.Thermal noise and shot noise are inherent …
19Quantum noise — is uncertainty of some physical quantity due to its quantum origin.In the case of number of particles (photons or electrons), the quantum noise is also called shot noise. Most optical communications use amplitude modulation. In this case, the… …
20Image noise — Noise clearly visible in an image from a digital camera Image noise is random (not present in the object imaged) variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the… …
