I came across this which i think is one amazing little circuit i plan on using a little modified on my multi system monitor...
I was shocked at how this simple circuit can duplicate in a way what some high frequency digital circuits and a ADC chips do but pretty much at the same line or frame rate frequencies you want if you replace the opamp oscillator with a sync pulse circuit .
you can see its a great little circuit for a scope tv or crt tv
original and newer videos below and pdf of the circuit
