The circuit for generating burst gate pulses by using only horizontal sync. signals comprises a latch (10) for latching a horizontal sync. signal (H-SYNC) and a burst control signal, a first combination unit (20) for combining the latch (10) output with the sync. signal (H-SYNC) to output a switching control signal (SCP), a second combination unit (30) for combining the inverted signal of the latch with the signal (H-SYNC) to output a burst gate pulse (BGP), a first switching unit (40) driven by the signal (SCP), a pulse width control unit (50) for controlling the output voltage according to the unit (40), a voltage comparator (60) for comparing the output voltage with a reference voltage, and a second switching unit (70) driven by the comparator (60) output to output the burst control signal (BCP)>
