Signaalikohinasuhde
Signaalikohinasuhde, often abbreviated as SNR or S/N, is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined as the ratio of signal power to noise power. A high signaalikohinasuhde indicates that the signal is strong relative to the noise, which is generally desirable for accurate measurement or communication. Conversely, a low signaalikohinasuhde means that the noise is significant compared to the signal, which can make it difficult to extract useful information.
The signaalikohinasuhde is typically expressed in decibels (dB) because it is a logarithmic scale. This logarithmic
