Signal-to-noise ratio is defined as the ratio of the power of a signal (meaningful information) and the power of background noise (unwanted signal): 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.he signal-to-noise ratio, the bandwidth, and the channel capacity of a communication channel are connected by the ShannonâHartley theorem. Signal-to-noise ratio is sometimes used informally to refer to the ratio of useful information to false or irrelevant data in a conversation or exchange.
