WebA Signal-to-noise ratio is a measure of the amount of background noise with respect to the primary input signal. It is formally defined as he ratio of signal power to noise power, and is often expressed in decibels. For example, a ratio of 1:1 indicates more signal than noise, and is greater than 0 decibels (dB).
