Signal to Noise Ratio

Posted by 31 August, 2009 Comments Off on Signal to Noise Ratio

Signal to noise ratio is a measurement that is used in electrical engineering and refers to the ratio of a particular signal power and the noise power that corrupts the signal. The ratio makes a comparison between the levels of a signal that is desirable to the level of the noise in the background.

When the signal to noise ratio is high, it means that the background noise is not very obtrusive. The signal to noise ratio is usually expressed in terms of decibels.

Signal to Noise Ratio

When this ratio is being calculated, the assumption is that the noise and signal are not statically related and come from different sources. When there is too much noise, the ratio is low but when the noise is less the signal to noise ratio is high.
