The ‘Signal-to-Noise’ ratio or, SNR (in short), is a metric that describes the signal performance in the presence of wireless channel noise (interference). In the linear scale, the SNR is the ratio of the signal power to the noise power. The wireless channel is never noise-free.

WebSuch a distribution has the property that its mean value is equal to its variance. Since shot noise is equivalent to the square root of the variance, for a signal consisting of n photons, the signal-to-noise ratio is given by: Signal-to-Noise (S/N) = n/(n1/2) = n1/2. In an ideal microscope, only the optical shot noise limits the image quality.
