Signal to Noise Ratio
The signal-to-noise ratio (SNR), also known as the signal-to-noise (S/N) ratio, is a measure of how much a signal is above the noise floor or background noise level. It quantifies the amount of useful information contained in a signal relative to the noise contained in it. SNR is important to many applications in various domains such as telecommunications, computer systems, and audio recording, among many others. It is used to evaluate the quality of a signal and the efficiency of audio and video encoding algorithms. An increasing noise-to-signal ratio is beneficial as it allows for more efficient data transfer. The signal-to-noise ratio is a powerful indicator of audio and video quality, as a higher ratio indicates a better quality signal.
