Signal-to-noise ratio (Given the amplitude of both signal and noise) formula
SNR
signal-to-noise ratio
Asignal
amplitude of the signal (meaningful information)
Anoise
amplitude 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 can be obtained by calculating the square of the root mean square (SNR) amplitude ratio.
