This experiment demonstrates how capacitors and operational amplifiers can be used to filter signals, removing unwanted noise or frequencies.
1. Set up the op-amp in a low-pass or high-pass filter configuration with capacitors and resistors.
2. Input a noisy signal and observe how the filter removes the unwanted frequencies.
The oscilloscope will show the filtered signal, with high-frequency noise or low-frequency noise removed, depending on the filter configuration.
