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
signal-to-noise ratio — Abbreviated SNR. The ratio between the desired signal and the unwanted noise at a specific point in a cable; a measure of signal quality. SNR is particularly important in networks using unshielded twisted pair cable (UTP). SNR… … Dictionary of networking
signal-to-noise ratio — noun a) A figure of merit comparing the strength of a signal carrying information to the noise interfering with it. b) A way of describing how much interesting information is included in a message or conversation. See Also: SNR, S/N … Wiktionary
Signal to noise — Das Signal Rausch Verhältnis (auch Störabstand a bzw. (Signal )Rauschabstand aR, oft auch abgekürzt als SRV beziehungsweise SNR oder S/N vom Englischen signal to noise ratio) ist ein Maß für die technische Qualität eines aus einer Quelle… … Deutsch Wikipedia
Signal-to-interference ratio — The signal to interference ratio (S/I or SIR), also known as the carrier to interference ratio ( C/I , CIR), is the quotient between the average received modulated carrier power S or C and the average received co channel interference power I ,… … Wikipedia
signal-to-noise — noun a) The ratio comparing signal power to noise power. b) The quantity of quality information compared to irrelevant or incorrect information. Syn … Wiktionary
Carrier-to-noise ratio — In telecommunications, the carrier to noise ratio, often written CNR or C/N , is the signal to noise ratio (SNR) of a modulated signal. The CNR is the quotient between the average received modulated carrier power C and the average received noise… … 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 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
