DIVIDING CIRCUIT FOR TELEVISION COMPOSITE VIDEO SIGNAL

The cireait includes a first low pass filter (2) for eliminating high frequency component of input signal, a sampling circuit (3) for eliminating curved part of low frequency signal, a first driveng circuit (7) for transmitting the output signal of a comparator (6) as data with a fixed level, a resonance circuit (a) for selecting a synchronous signal with a particular frequency from synthesized video signal, a second driving circuit (12) for modulating output signal of a comparator (11) to rectangular signal with a certain level, a second low pass filter (13) for filtering horizontal synchronous signal, and a synthesized synchronous dividing circuit (14) for generating a pulse by being off-state .
