A Q-multiplier is a regenerative stage.

It's prime was in the days of the 455KHz IF, where the improved

would actually make a difference. At a higher frequency, it would still
increase the selectivity of the tuned circuit, but not enough to narrow
the passband for voice or CW.

So what about audio Q-multipliers? Do they function on the same principle?
