Abstract
In a color signal processing circuit capable of processing a PAL/NTSC color television signal, in order to prevent an image deterioration caused by chromatization when a signal is received in an NTSC signal receiving mode, there is provided a gate control signal generating circuit for alternately generating gate control signals 'GA' and 'GK', one for one horizontal period and the other for a next one horizontal period, in response to application of a phase inverting pulse 'R' which inverts in polarity every one horizontal period.
