NOTES:
b. The composite sync output reproduces all the video input sync pulses, with a propagation delay.
c. Vertical sync leading edge is coincident with the first vertical serration pulse leading edge, with a propagation delay.
d. Horizontal sync output produces the true “H” pulses of nominal width of 5µs. It has the same delay as the composite sync.
