Remark
Spot noise figure: |Ratio of 1) the total output noise power per unit bandwidth (spectral density) at a single output frequency when the noise temperature of all input terminations is at the reference noise temperature T_no} at all frequencies that contribute to the output noise, to 2) that part of Item 1) caused by the noise of the signal-input termination at the signal-input frequency.
