ivconic Interesting PI. Schematic
but i think this is a old verssion schematic what is the coil inductanc & diameter of coil

[ivconic]

I said: "Interesting PI. Schematic?"
Two sentences. First that it is interesting PI. Second "Schematic?" - meaning " anybody have schematic for this?"
So i dont have schematic and dont know nothing more about this PI. I just have this pcb pattern and nothing else.

Regards!

Hi Ivica. Can you attach the schematic (no the pcb)???

[Geo]

I just saw your second reply

[Geo]

But with 741 as first stage amplifier, it is not a interesting PI design.

[ivconic]

Why? You can always use some other opamp.

How i missed that schematic??
Patrick you are the CHAMPION!
Thanks much!

[Geo]

There is a difference. It has not the dual op.amp LM358 and it has the 741, so something is missing

Hi Geo
Schematic help us, first stage is LF357 , good choose . it is fast opamp
Best regards.

Other thing , it had discrimination.
Best regards.
