Excess noise ratio
text:
In electronics, excess noise ratio is a characteristic of a noise generator such as a "noise diode", that is used to measure the noise performance of amplifiers. The Y-factor method is a common measurement technique for this purpose. By using a noise diode, the output noise of an amplifier is measured using two input noise levels, and by measuring the output noise factor the noise figure of the amplifier can be determined without having to measure the amplifier gain.
