Question

defination of signal to noise ratio with formula

Answer 1

Signal-to-noise ratio (abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of backgroundnoise. S/N ratio is defined as the ratio of signal power to the noise power, often expressed in decibels.

Answer 2

Answer:

In terms of definition, SNR or signal-to-noise ratio is the ratio between the desired information or the power of a signal and the undesired signal or the power of the background noise. In other words, SNR is the ratio of signal power to the noise power, and its unit of expression is typically decibels (dB).
