When Using a Noise Diode Generator in Making Noise Measurements

Multiple Choice

When using a noise diode generator in making noise measurements, the noise diode's current in ma. is numerically equal to the:

A) noise ratio of the DUT only if its impedance is 50 ohms.
B) noise figure in decibels of the DUT only if its impedance is 50 ohms.
C) noise ratio of the DUT no matter what its impedance is.
D) noise figure in db of the DUT no matter what its impedance is.
