Hi all, discussion on class D amplifiers has become more common recently on the forum. Am I the only one who a) has never seen or worked on one yet? b) doesn't understand how they work? I am used to the usual class A, B and C amplifiers which have been around for a long while, but can't get my head around an amplifier which can work well beyond cutoff, if that's actually how they work. Possibly use some kind of pulse width/amplitude system? Someone please enlighten me! Thanks in advance.
Alan.
