Support the channel: In this series, I'm taking a detailed look at how to build an analog VCF from scratch. To keep it as beginner-friendly as possible, I'm explaining what all the components do in detail.
This first part deals with passive first- and second order high & low pass filters. If you want to follow along, here's a bill of materials:
1x 1M mono potentiometer
1x 1M stereo potentiometer
1x 47k resistor
2x 10 nF capacitor
2x jack socket
