SNR is imperative to distinguish various output signals to achieve efficient output. Signal-to-Noise Ratio is typically expressed in terms of decibels. The higher the SNR value, the better is the output.

WebFor decades now, HORIBA Scientific has defined the SNR as the difference of Peak signal minus Background signal, divided by the square root of the Background signal.
