That's why they're called a "class" since everyone knows the output is AB.

The word "class" has several meanings. One of them has an implication that
is different from "type". Class A -- conduction through the full cycle -- is
not called A by accident.

That's a very restricted use applying only to A, B and C.


They might be true, but that wasn't the point I was making. There is
such a thing as "product differentiation", and you don't make yourself
look different by appearing to copy someone else's feature.

Class G and H achieve similar results by different means. The distinction
is REAL not marketing.

But that isn't the point. If company A used the same circuit

Do you mean 'topology' rather than circuit ?


as company B, it would be foolish for them to use the same designation.

But they DO ! Very many brands of Class G and H amps exist ! G or H describes
the method used to reduce dissipation in the output stage.


That was the point, not whether "class" G and "class" H are the same or
different.

I don't even begin to understand that statement, sorry.

Did you read the wikipedia link btw ?
