    Too basic, I'm not sure anyone needs that to solve the task as basic would need to read an article, it's obvious.

    In any serious installations (more than a homelab) you want some numeric metrics, not eyeballing. E.g. management or next engineer may reasonably ask "why alpha is 0.8? what's the rationale, why not 0.85", you want some formula to show it's what we want.

        OT but I've always appreciated your posts, Jason -- you should think about expanding them into a book, or at least an e-book. It would end up on my shelf next to Lyons.

        That being said, it'd be good to update this post to clarify the difference between angular frequency and plain old cycles-per-second frequency, as one of the commenters calls out.
