Signal-to-noise ratio (Given signal mean or expected value and standard deviation of noise)

Formula

Signal-to-noise ratio (Given signal mean or expected value and standard deviation of noise) formula
SNR
signal-to-noise ratio
mu
the signal mean or expected value
sigma
the standard deviation of the noise, or an estimate

Formula description

An alternative definition of SNR is as the reciprocal of the coefficient of variation, i.e., the ratio of mean to standard deviation of a signal or measurement.
