Circuit Diagram Converter trigger signal causes the 555 to discharge the capacitor for synchronization
LM1881 is used to do all the grunt work of separating the sync signals from the composite video. The chip provides the vertical sync on pin 3 for the vertical oscillator, and composite sync on pin 1 for the horizontal oscillator. The intensity signal comes from the composite video signal itself, but is negative. I […]
