Signal to noise ratio. SNR (signal-to-noise ratio) is the comparison between the highest signal level emitted and the noise that comes out from the outlet of the equipment. This term represents the proportion between the strength of the unwanted noise and the audio signal emitted. The greater the distance between them, the better the signal to noise ratio is.

The stimulus tone is then filtered from the output of the device with a sharp notch filter and the level of the remaining noise products is expressed as a ratio to the level of the full scale signal. Signal to noise ratio and dynamic range are usually the same for linear devices such as amplifiers, but for time-varying devices such as systems using dynamic compression or …

Signal-to-Noise Ratio (SNR): Refers to the ratio between a recorded signal and the noise levels associated with it. Think of a conversation (signal) at a cocktail party (noise). The higher the signal-to-noise ratio the better the quality of the audio. [ Audio Glossary ]
What is Signal-To-Noise Ratio (SNR)?

A ratio bigger than 1 dB indicates that the signal is more than the noise. Conversely, if the ratio is less than 1, it indicates that the noise level is bigger than the signal level. If the power of the signal is less than the power of the noise, i.e. the SNR < 1, the signal becomes unusable. When an audio component for example has a SNR of 100 dB, it means that the level of the audio signal …

In other words, SNR is the ratio of signal power to the noise power, and its unit of expression is typically decibels (dB). Also, a ratio greater than 0 dB or higher than 1:1, signifies more signal than noise. Aside from the technical definition of SNR, the way I define it in other terms is by using a comparative.
What is signal-to-noise ratio and how is it measured?
https://www.techtarget.com/searchnetworking/definition/signal-to-noise-ratio
A signal-to-noise ratio over 0 dB indicates that the signal level is greater than the noise level. The higher the ratio, the better the signal quality. For example, a Wi-Fi signal with S/N of 40 dB will deliver better network services than a signal with S/N of 20 dB. If a Wi-Fi signal's S/N is too low, network performance can be impacted because it becomes more difficult for …

This determines the signal-to-noise ratio (SNR) of the system. In particular, the bandwidth is f s /2, where f s is the sampling rate, and the SNR is given by (6.02 N + 1.76) dB, where N is the wordlength in bits.

Signal-to-Noise Ratio (or SNR) Signal-to-noise ratio (abbreviated SNR or S/N) is a measure used in science and engineering circles that compares the level of a desired signal to the level of background noise. Digital TV tuners (like those in your TV and in your Tablo DVR) will generally process signals from about -50 dBm (strong) to about -80 dBm (weak).
