Signal-to-Noise Ratio (SNR)

All analog electrical circuits introduce some amount of background noise or hiss to the signal path. The signal-to-noise ration (SNR) is the ratio of background noise (e.g. hiss) to direct signal. A high ration means not much noise and a low ratio means lots of noise. Correct use of gain staging (setting the levels correctly) can greatly reduce the amount of noise introduced in the signal path.
