Term: equivalent spot noise temperature, <of a linear two-port>
Synonym1:
Synonym2:
Synonym3:
Symbol: T(f)
Definition: amount by which at a given frequency the spot noise temperature of a one-port connected to the input of a given linear two-port would have to be increased, if the noise due to this two-port were temporarily suppressed, in order to cause the noise power spectral density, at the output frequency corresponding to the input frequency, to be the same as that of the total noise of the one-port and the given two-port

Note 1 to entry: This definition assumes that quantum effects are negligible.

Note 2 to entry: The equivalent spot noise temperature of a two-port is dependent on the impedance of the one-port connected to its input.
