- An amplifier has input and output impedances of 75 ohms, 60 dB power gain anc a noise equivalent bandwidth of 15 KHz. When a 75 Q resistor at 290°k i connected to the input, the output rms noise voltage is 75 u v. Determine the effective noise temperature of the amplifier assuming that the meter is impedanc matched to the amplifier.
