Converting from a difference equation into a b and a coefficient/vector representation is quite straightforward once you see it it action. This video just shows a few examples
Glad to see you active again! Your videos are definitely the most thorough and detailed on youtube! I have a request tho.. Could you do a video on how to read math equations? Like say for pitch detection methods like auto - correlation etc ? I know how to code these by understanding how they work, but when i see them as a math equation i can never connect each aspect of equation to code!
I don't think you're alone there. A lot of algorithms (like auto correlation) are described mathematically and it can often take some time to decipher the math equation. I'll definitely add this request to the TO DO list but I'm not sure when I'll get round to it though.
