Here is the part-1 article
In the second part of the active low pass filter analysis videos, 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 around 722Hz, however, in practice, the result would be different. The cut-off frequency of a filter is where the X-Axis (frequency) meets the Y-Axis (amplitude) at the -3dB point. The Siglent SDS2000x plus series oscilloscopes offer tons of features for bode plot analysis in practice.
