In analog and digital communications, signal-to-noise ratio, often written S/N or SNR, is a measure of signal strength relative to background noise[;] the ratio is usually measured in decibels (dB).

OBS

This ratio is usually in terms of peak values in the case of impulse noise and in terms of the root-mean-square values in the case of random noise.

OBS

This ratio may be a function of bandwidth of the transmission system.

OBS

signal to noise ratio; SNR: term and abbreviation officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).
