In this video, I used the bode plot to analyze the low pass active filter's behavior in practice. There are not many devices that can calculate and demonstrate the bode plot. I used Siglent SDS2102X Plus oscilloscope to plot the bode curve. The cut-off frequency of the filter, in theory, is...
In this video, I explain some theories behind a low pass active filter circuit, then I built a simple active low pass filter using the LM358 opamp. I tested the filter's behavior using the Siglent SDG1025 waveform generator and the Siglent SDS2102X Plus oscilloscope.
