Styles 1. 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 sensitive meter at the output reads 240 μV rms. Assuming operation at 37° C, calculate the resistance of the resistor. If the bandwidth were cut to 25 kHz, determine the expected output meter reading. (Ctrl) -
