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 V 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) -

Question
**Amplification of Resistor Noise** The noise produced by a resistor is to be amplified by a noiseless amplifier with 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, the task is to calculate the resistance of the resistor. Additionally, if the bandwidth were reduced to 25 kHz, the expected output meter reading should be determined. **Diagram Explanation:** There is a simple electrical circuit symbol, which typically represents a ground or reference point, but no complex diagram or graph is present.
