Also, SNR is a measurement parameter in use in the fields of science and engineering that compares the level of the desired signal to the level of background noise.
- signal-to-noise ratio (S/N or SNR) - TechTargetIn analog and digital communications, a signal-to-noise ratio, often written S/N or SNR, is a measure of the strength of the desired signal relative to background noise (undesired signal). S/N can be determined by using a fixed formula that compares the two levels and returns the ratio, which shows whether the noise level is impacting the ...
- Signal-to-noise ratio - WikipediaSignal-to-noise ratio (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. SNR is defined as the ratio of signal power to noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise.

- Signal-to-noise ratio - MATLAB snr - MathWorksThis MATLAB function returns the signal-to-noise ratio (SNR) in decibels of a signal xi by computing the ratio of its summed squared magnitude to that of the noise y: r = mag2db(rssq(xi(:))/rssq(y(:))). y must have the same dimensions as xi.
