Signal to Noise Ratio is an electrical engineering
measurement defined as the ratio of a signal power to the noise
power corrupting the signal.
Signal-to-noise ratio compares the level of a desired signal (such
as music) to the level of background noise. The higher the ratio,
the less obtrusive the background noise is.
In electronics, a signal is an electric current or electromagnetic
