Hi,
I didn't have much luck, unfortunately, with the provided sync separation circuit in the NBTV handbook so I've been experimenting with my own. I don't mean to imply the original doesn't work, I just didn't manage to get it going. Probably my own fault. I'll give it another go to see if I can get it going, my design isn't without flaw.
It takes a negative video input and provides a positive going pulse. I'm interested in your opinions of the circuit and how it may be improved, if at all.
I'm a student at TAFE in Adelaide. We haven't covered op-amps yet but that hasn't stopped me from going further
Thanks.
