| titleOfInvention | Equivalent pulse period invalidity discrimination circuit |
| abstract | (57) [Abstract] [Purpose] It is an object of the present invention to provide an equivalent pulse period invalidity determination circuit which enables a horizontal frequency determination circuit to correctly determine the frequency of a horizontal synchronization signal. When the frequency of the horizontal synchronization signal is determined by the horizontal frequency determination circuit A from the composite synchronization signal in which the equivalent pulse is inserted in the vertical blanking period at a half cycle of the horizontal synchronization signal, the equivalent pulse period During the period when the equivalent pulse detected by the detection decoder 23 exists, the horizontal frequency discrimination operation by the horizontal frequency discrimination circuit A is invalidated based on the output of the horizontal frequency discrimination invalid period generation circuit 24, and this operation is performed by the latch pulse enable circuit 25. It is prohibited by the output of. |
