Many people wonder why the integrator is different from all other circuits. This is new and I assure you that it works great. It is not good for 30 years to look at the same schemes.

I really know bad English. Why not learn Bulgarian?

The signal integration is made from R8 C9 and C14 R22. Via resistor R18 the capacitor C8 is charged to the difference between the voltage on C9 and the input voltage of the non-inverting input. This occurs for a time that signals a signal. C16 and R31 work the same way.

Yes, thanks very much for that. But please tell us why did you choose such an exotic integrator? Couldn't this have been done with regular low pass integrator topology. Is there any special reason for choosing a bandpass dual feedback integrator? Especially since you are first one to use such in a PI circuit(the ones I have seen). Or did you just pull it out of a hat.
If I want to know how an integrator works, I can got to wikipedia.
I want to know the design choices you made and why.

Ah, Master Jedi, I have provoked you out of your long slumber!
Please explain your integrators, how they work. you can say in Bulgarian, no problem. I will use translator.

For your information, my profession is related to machine programming. There are many people with wooden heads here ...

Or maybe he's an old crank, just fiddling around with vacuum tube amplifiers. Never programmed a micro in his life. An old analog man who's past his prime.
I hope he has a sense of humor.

Hey all

Why do you spend money and life time on totaly unuseful project - Bulgarian Sand Banks ? I am out of text.

Wanna know how to make good, stabile design, deep searching MD with GB and auto FB desaturation circuit, study or better build some of best Pi in the world already posted at this forum.

But what for example?

All projects of Mr.Irishman Eric Foster and also from German EE which made original Pulse Star. There are also several interesting Russian projects and original Zed's SD2000.
Bets way to make superb MD is first make one same like original, then modify it according to your needs. All other projects including Bulgarian clones whatever PI or VLF are pettite string beans.

That's all.
Good luck

It was the unusual integrators which got my attention.
SCS does not strike me as a daft individual just out to peddle his little circuits around the place. No, no, quite the contrary, this man very well knows his stuff. I suspect there is a whole lot more hidden under the surface of this little iceberg.
He probably has a very much more advanced design he keeps for himself, what he posted here was the baby version.

Thanks Carl.
