Hey y'all
I'm trying to attenuate a 5v envelope in a way that I'm not sure is possible in the analog realm.
I've attached a photo to help explain my intentions.
Ultimately, when the pot is fully CW, I want the envelope to go from +5v to 0v.
When pot is center, I want the envelope to sit at 0v (as if it's fully attenuated down)
And when the pot is fully CCW, I want the envelope to go from 0v to +5v.
The closest thing to this I'm aware of is an attenuverter.
However, its my understanding this would result in the following:
Fully CW = +5v to +2.5 envelope
Center = +2.5v
Fully CCW = 0v to +2.5v
My first thought is to generate two envelopes - one from +5v to 0v and the other flipped over +2.5v that goes from 0v to +5v.
Then mixing the two signals with a pot - however I'm not sure about how to have a centered pot result in 0v.
Any insights on how to do this, or am I wasting my time?
Thanks
