Signal-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… … Wikipedia
Signal to noise ratio (image processing) — The Signal to Noise Ratio (SNR) is used in image processing as a physical measure of the sensitivity of an imaging system. Industry standards measure SNR in decibels (dB) and therefore apply the 20 log rule to the pure SNR ratio. In turn,… … Wikipedia
Contrast-to-noise ratio — Haze over Kuala Lumpur. Contrast to noise ratio (CNR) is a measure used to determine image quality. CNR is similar to the metric, signal to noise ratio (SNR), but subtracts off a term before taking the ratio. This is important when there is a… … Wikipedia

Noise measurement — is carried out in various fields. In acoustics, it can be for the purpose of measuring environmental noise, or part of a test procedure using white noise, or some other specialised form of test signal. In electronics it relates to the sensitivity … Wikipedia
Noise figure — (NF) is a measure of degradation of the signal to noise ratio (SNR), caused by components in a radio frequency (RF) signal chain. The noise figure is defined as the ratio of the output noise power of a device to the portion thereof attributable… … Wikipedia
Noise shaping — is a technique typically used in digital audio, image, and video processing, usually in combination with dithering, as part of the process of quantization or bit depth reduction of a digital signal. Its purpose is to increase the apparent signal… … Wikipedia
Noise (audio) — Noise in audio, recording, and broadcast systems refers to the residual low level sound (usually hiss and hum) that is heard in quiet periods of a programme. In audio engineering, it can refer either to the acoustic noise from loudspeakers, or to … Wikipedia
Noise equivalent temperature difference — (NETD) is a measure of the sensitivity of a detector of thermal radiation in the infrared, terahertz radiation or microwave radiation parts of the electromagnetic spectrum. It is the scene temperature difference equal to either the internal noise … Wikipedia
Noise 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… … Wikipedia
