    Noise physics and telecommunications. In heterodyne systems, output noise power includes spurious contributions from image- frequency transformation, but the portion attributable to thermal noise in the input termination at standard noise temperature includes only that which appears in the output via the principal frequency transformation of the system and excludes that which appears via the image frequency transformation.

    From the definition of noise factor [3]. The first amplifier in a chain usually has the most significant effect on the total noise figure because the noise figures of the following stages are reduced by stage gains.

    Attenuators have a noise factor F equal to their attenuation ratio L when their physical temperature equals T 0. Consequently, the first amplifier usually has a low noise figure, and the noise figure requirements of subsequent stages is usually more relaxed.

    Noise figure NF and noise factor F are measures of degradation of the signal-to-noise ratio SNRcaused by components in a signal chain. Low noise amplifies LNA fundumentals 14 - Duration: Add to.
