Noise Temperature Of Attenuator at Maurice Amanda blog

Noise Temperature Of Attenuator. A proof of this statement is provided here. The noise temperature of an amplifier refers to the noise that would be added at the amplifier's input (relative to the input impedance of the amplifier). What is the equivalent noise temperature t e or noise figure f of a passive device (i.e., not an amplifier) ? In general, terms such as noise figure and noise factor should only be applied to wireless receivers, since the noise power from an antenna at 290k. Determine the effective noise temperature of an attenuator with losses a) 1.0, b) 1.25 and c) 10.0 (all linear power ratios). It is known that the noise figure of an attenuator is equal to its attenuation coefficient l. Thermal noise is a random fluctuation in voltage caused by the random motion of charge carriers in any conducting medium at a temperature above absolute zero (k=273 + °celsius). The output effective noise temperature, \(t_{\text{eff}}\), is the temperature of a resistor that would produce the same available noise power,. In this example the source has a noise temperature.
