* Signal 1a drawing reproduced with permission from EIA.
b. The composite sync output reproduces all the video input sync pulses, with a propagation delay.
d. Odd-even output is low for even field, and high for odd field.
e. Back porch goes low for a fixed pulse width on the trailing edge of video input sync pulses. Note
c. Vertical sync leading edge is coincident with the first vertical serration pulse leading edge, with a
propagation delay.
that for serration pulses during vertical, the back porch starts on the rising edge of the serration
pulse (with propagation delay).
