Reference no: EM131206684

Referring to (A.37) and the accompanying discussion, suppose that two calibrated noise sources have effective temperatures of 600 K and 300 K.

a. Obtain the noise temperature of an amplifier with these two noise sources used as inputs if the difference in attenuator settings to get the same power meter reading at the amplifier's output is 1 dB, 1.5 dB, or 2 dB.

b. Obtain the corresponding noise figures.
