[Diy_efi] I need to rectify a low ac voltage.

[Jörgen Karlsson]

Hi,

I need to measure an AC voltage in the 50-500mV range with a micro
controller. This is for reading the impendance of the sense cell in a bosch
LSU (or NTK UEGO) sensor.

Can anyone please help me to rectify and filter the signal, I can't come up
with a good way to do this.

Jörgen
