Signal-to-noise ratio (Given the power of both signal and noise in decibels)

Formula

Signal-to-noise ratio (Given the power of both signal and noise in decibels) formula
SNRdB
signal-to-noise ratio in decibels
PsignaldB
average power of the signal in decibels
PnoisedB
average power of the background noise in decibels

Formula description

Because many signals have a very wide dynamic range, for example, in decibels, SNRs are often expressed using the logarithmic decibel scale.
