Hello friends, I am Aldo. I need measure the envelope of a signal, from 2 hz to 500 hz, as accurate as possible. I tried many circuits made by me, and many that I saw on electronic pages, and honestly none works as it should.
Can someone help me ?, did anyone try a circuit that really works well ?. Using only one diode, with capacitor and a ground resistor does not work, it does not work well.
I need a precision circuit, with operational amplifiers.
Thank you very much !!!
