Video Pre-amplifier and Sync Separator PCB board
Printed circuit board for easy construction of a 3x video pre-amplifier and sync
separator. The sync separator generates clamping pulses as needed by the active
clamping circuit in the LED/neon driver board.
A completely populated PCB is shown here.
All components are easily obtained.
Block diagram of the circuit. A line pulse and a frame pulse (after the missing
sync pulse) are the output signals The line pulse can be used as a clamping
