Does this work?

The circuit from this thread ; https://www.electro-tech-online.com/threads/complementary-square-waves-creation.93765/ is exactly what I need for a project. The OP said he would post if it worked, but never did.

What I want to know does it work? It looks like it will but I'd like a conformation, please.
It was posted by MikeMl. MikeMl have you used this as part of a circuit? Thanks.

The picture is too small to see.

I don't know why it won't enlage? I'll try this

It splits the input pulses so that each second pulse input is transfered to output A and the other half is transfered to B.

Reminds me about a demux, but it's not. I dont know how to possible use such a circuit. Nice if anybody having an idea how to use it

It will work as drawn.

neat. You're still playing around with memory devices and logic gates. Kinda ancient stuff, but cool too.

Take a close look at the main board of your PC. It's stuffed with ancient logic gates.

well, I meant at that level. TTL devices at their lowest representation symbol..

I wouldn't call the logic gates inside an FPGA on a motherboard ancient.

Thank you, Mike. This is what I've been looking for. Boy are there a TON of posts in the archives here! I like to try to find stuff on my own before bothering you guys.

I'm going to use it to make an Electrical Discharge Machine. This will allow me to turn on alternating mosfets to charge and discharge two capacitor banks. The capacitors will be connected to a shaped electrode to machine metal.

well he ain't using an FPGA ain't he? I thought he'll be using AND gate and flip-flop ICs...

I was responding to Boncuk who mentioned a PC motherboard.

EDIT:
I've added a quote.

... who was responding to me. Hehee..

Quote myself

I think if I where going to make a driver for a push-pull transformer with basic components (no µPC) then using this circuit would make sense. If adjacent pulses is of same duration, then it should resolve problems with unbalanced DC in transformer. Assuming changes over time won't affect this balance particularly.

I assume if the circuit is possible to expand, so that it split the input pulses out to three separate outputs- then it would make it pretty easy to do PMW on a reluctance motor.

I have redrawn the circuit. Looks pretty nice, doesn't it?

Does this work?
