Abstract

PURPOSE: To make stable the synchronism, by rejecting noise component during horizontal scanning period due to ghost signal.
CONSTITUTION: The synchronizing pulse 8 from the TV signal 7 picked up at the synchronizing separation circuit 6 is fed to the vertical (horizontal) synchronizing pulse detection circuit 3(4) and other required circuits. When the circuit 4 discriminates the horizontal synchronizing pulse with the clock from the clock circuit 1 and the pulse width of the synchronizing pulse 8, the output of the circuit 4 is taken for AND11 condition with the output from the frequency dividing circuit 9 to output the horizontal synchronizing pulse. To the circuit 10, the output of the counter 2 and circuit 9 and the synchronizing pulse 8 are fed and as the result of logical sum, the horizontal synchronizing signal rejected for noise due to ghost can be obtained. Excellent synchronizing performance can be obtained by using this for the synchronism of a TV receiver.
