5. The noise output of a resistor is amplified by a noiseless amplifier having a gain of 60 and a bandwidth of 20KHz. A meter connected to the output of the amplifier reads 1mVrms (a) the bandwidth of the amplifier is reduced to 5KHz, its gain remains constant. What does the meter read now? (b) If the resistor is operated at 80 degrees Celsius, what is its resistance.
