Effective input noise temperature
In telecommunications, effective input noise temperature is the source noise temperature in a two-port network or amplifier that will result in the same output noise power, when connected to a noise-free network or amplifier, as that of the actual network or amplifier connected to a noise-free source.If F is the noise factor numeric and 290 K the standard noise temperature, then the effective noise temperature is given by T n = 290(F − 1).This article incorporates public domain material from Federal Standard 1037C.General Services Administration.This article related to telecommunications is a stub.
