WebS/N = 20 log 10 (P s /P n) P s is the signal in microvolts, and P n is the noise in microvolts. However, if the signal and noise are measured in watts, the formula is slightly different: S/N = 10 log 10 (P s /P n) The letter P is often used in these formulas to indicate power. When P s equals P n, S/N will be 0.
