Handbook Sync Circuit
Posted: Fri Aug 03, 2018 1:42 am
I wanted to know if any of could maybe answer a couple questions about this circuit.
I like this circuit and have used the portion at IC1b to grab the sync signal. I am using 5v instead of 12v.
But I am puzzled why we would put a capacitor (C2) on the video line. Wouldn't that mess up the signal some? Stretch out parts?
IC1a speaks of restoring the signal. Is that going to affect IC1b? That part of the circuit is puzzling me. Are we trying to amplify the signal?
It seems I should be able to remove IC2 and just have a logic level Mosfet fire off of the positive signal line (going into pin 3 of IC2).
I am planning to use 6 super bright Led's as that circuit has. would you use 1w resistors there? The positive would be coming from 12v.
I am not an analog guy really and I am trying to navigate to some degree. I know that a lot of circuits are made for regular Mosfets and not logic level ones.
Thanks for any advice you might be able to offer.
