What is Signal to Noise ratio?
Answer:
1.S/N or SNR is a measure of signal strength relative to background noise.

2.The ratio of the amplitude of a desired signal to the amplitude of noise in a transmission channel at a specific point in time.

3.S/N ratio or SNR is an important specification, and is widely used as a measure of receiver sensitivity.

4.Signal-to-noise ratio is defined as the power ratio between a signal (meaningful information) and the background noise (unwanted signal):SNR=Psignal/Pnoise.

SNR use to measure the performance of a receiver.
