Noise Figure

Noise figure (NF) is a measure of degradation of the signal to noise ratio (S/N), caused by components in a radio frequency signal chain. It is a number by which the performance of a radio receiver or system can be specified. The noise figure is simply the noise factor expressed in decibels (dB).
