Hello everybody,
I'm looking for long time for a simple and complete envelope detector. I give you the detail : I would like to make an envelope follower stage so as to control the cutoff frequency of a filter. I'm looking for an envelope follower that could have attack and decay time setting, and I don't find any schematic or PCB at all ! (or maybe I search badly, but I saw hundreds of schematics without finding what I'm looking for lol)
I'm not very skilled in electronic, but I know I can make a simple peak detector with a diode, resistor and a cap, or a full wave rectifier with op-amp also.. but I never find something with attack and rekase time control.
I also looked to the THAT RMS detector chips, and in that way I searched for a peak envelope detector IC .. but I found nothing.
So, I'm wondering if I misundestood something... maybe this is not realisable.. ?
Do you have any idea or simple design for that kind of envelope generator (I could try to do it on a veroboard) , or if you have a PCB schematic :grin:
Thank a lot for your help :thumb:
