摘要:
A signal generator for generating a clocked PAL reference video signal from a single signal source. A counter-divider (30) extracts subcarrier frequency component from the PAL reference video signal and a frequency changer (34) in combination with a counter-divider (38) extracts a horizontal frequency component from the PAL reference video signal.
