In this experiment, we analyzed the frequency response of several signals. Using an op-amp, we built a summing circuit, and by injecting various signals into the op-amp’s input, we analyzed the resulting signals at the output using an oscilloscope in FFT mode. The purpose of this experiment is to continue a series of related studies we started after completing our oscilloscope course, aiming to generate more content and motivate those involved in this study and related fields, with the goal of producing articles in the future.
