Abstract

PURPOSE: To obtain the rapid stability of hue by adopting a first burst gate pulse with a wide pulse width when a head switch pulse is switched or in a prescribed period from a vertical synchronizing signal is kept, and adopting a second burst gate pulse with the narrow pulse width in the other period.
CONSTITUTION: A circuit including a head switch pulse input terminal 17, a monostable multivibrator circuit 18 and a switch circuit 19 is the circuit for the burst gate pulse showing a period in which a phase comparator 20 is operated. The head switch pulse is inputted to the input terminal 17, and the monostable multivibrator circuit 18 generates the pulse of a 16H (H shows a horizontal scanning period) period from the switch. The switch circuit 19 selects a first wide burst gate pulse in the 16H period, and selects the narrow second burst gate pulse in the other period. The phase comparator 20 operates in the burst gate pulse period from the switch circuit 19. Thus, feedback gain can be improved and the hue can rapidly be stabilized.
