This video shows how to make a high pass filter starting with a simple voltage divider. It's almost the same as the low pass filter I did in the previous video. I show you how to calculate the transfer function and the corner frequency.

  • Awesome! I'm thinking of building a simple high-pass for my synth. If I put a potentiometer into this circuit where the resistor is, would that allow me to sweep the cut-off frequency? I know it wouldn't have a filter sweep effect because that involves a band of EQ rather than a simple cut-off, but it seems like it would be nice to be able to change the cut-off frequency that way.

  • nice keep em coming :)

  • Thank you for the video! I study Electronic Engineering at University of Brasilia (Brazil) and I thought it was very helpfull. Why don't you make a video of second order circuits?
