In this, our second tutorial video about filter design, we build on the topics that we covered in the last video. This time we take you through the steps to design a state variable filter of a fixed frequency. As a bonus, we also cover some of the nuances of prototyping precision analogue circuits.
The spreadsheet we talk about in the video can be found here, and should get you started with designing your own filters.
Following on from this in the next video we’ll start to investigate some of the techniques for making variable filters, controllable by a microcontroller or from analogue electronics.
