The F-word - or, why there is no such thing as too much feedback

Feedback is at once a basic subject in engineering and a remarkably polarizing one in audio with some saying it is evil and others saying that there is nothing wrong with it as long as you don't overdo it. Bruno Putzeys finds himself in a camp all by himself, but not exactly in the middle. This article tells you what is a fast' amplifier and what is a slow' one and whether they are really different; explains how the cause of SID lies outside (and can be solved outside) the feedback loop and provides some interesting historical background as to how audio engineering got into the mess it is in today.
