What is Signal to noise ratio?

Answer Posted / srikanth

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).

If the incoming signal strength in microvolts is Vs, and the
noise level, also in microvolts, is Vn, then the
signal-to-noise ratio, S/N, in decibels is given by the formula

S/N = 20 log10(Vs/Vn)
