The attack time constant is 1 ms and the decay time constant is 1 second, if I remember correctly

Kinda like a vu meter. Don't remember about the decay time. There is an analytical formula. Alas, I can't find my copy. I think it came from some old HP app notes. You are right in that the most important is the rise time. - Robert - On Tue, 23 Aug 2005 12:51:27 -0500 Ken Javor <[email protected]> wrote: > The quasi-peak detector is characterized by a charging > time constant and a > discharge time constant.
