A CIRCUIT FOR TREATING THE SYNCHRONIZED SIGN OF A MONITOR

摘要

A circuit for processing a horizontal synchronizing signal of a monitor is disclosed. The circuit comprises a horizontal synchronizing signal generation unit(10) for generating the horizontal synchronizing signal based on an inputted horizontal synchronizing signal and vertical synchronizing signal; a unit(20) for determining the magnitude of the horizontal synchronizing signal; a unit(30) for generating a reference voltage; a unit(40) for amplifying the magnitude of horizontal synchronizing signal over the reference voltage; and a unit(50) for enabling the horizontal synchronizing signal to be stable in case that the horizontal synchronizing signal from the amplifying unit does not exist.
