OverviewDefinitionAlternative definitionModulation system measurementsNoise reductionDigital signalsOptical signalsTypes and abbreviationsOne definition of signal-to-noise ratio is the ratio of the power of a signal (meaningful input) to the power of background noise (meaningless or unwanted input): where P is average power. Both signal and noise power must be measured at the same or equivalent points in a system, and within the same system bandwidth. The signal-to-noise ratio of a random variable (S) to random noise N is:
