Abstract

PURPOSE: To make it possible to prevent the malfunction from being generated due to undesired false pulses by detecting undesired false pulses by a detector circuit and resetting a sampling pulse generator circuit.
CONSTITUTION: In a vertical blanking interval, vertical synchronizing pulses are extracted in 1 from TV signals where information signals are inserted to specific lines after the part of vertical synchronizing pulses and equalizing pulses, and sampling pulses are generated in 5 after a prescribed time on the basis of this output in respect to time. In this case, when undesired pulses which are false to synchronizing pulses are inputted, they are detected by detector circuit 6, and pulse generator circuit 5 is reset by this detection output. As a result, the malfunction can be prevented from being generated due to undesired false pulses.
