The noise produced by a resistor is to be amplified by a noiseless amplifier having a voltage gain of 75 and a bandwidth of 100 kHz. A meter connected to the output of the amplifier reads 240 μV RMS. Assuming operation at 37°C, calculate the resistor’s resistance. In the previous problem, if the bandwidth were cut to 25 kHz, determine the expected output meter reading. A. 240 μV B. 60 μV C. 120 μV D. 75 μV
