Term Description
SNR SNR or S/N (Signal-to-Noise Ratio)
In communications, signal-to-noise ratio is a measure of signal strength relative to background noise (measured as signal level divided by noise). The ratio is usually measured in decibels (dB).

Higher SNR numbers repesent cleaner signals, with less noise. Decreasing noise, and/or increasing signal increases/improves the SNR value.
