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