Pnoise
average power of the background noise (unwanted signal)

Formula description

One of the most important components of analytical chemistry is maximizing the desired signal while minimizing the associated noise. The analytical figure of merit is known as the signal-to-noise ratio (S/N or SNR), which is defined as the power ratio between a signal (meaningful information) and the background noise (unwanted signal).
