Abstract

PURPOSE:To realize circuit constitution having less distribution capacity of wiring, etc. plus inductance, by utilizing the multiplication output of a color burst signal inverted in every one horozontal scanning period and chrominance subcarrier wave signal. CONSTITUTION:A color burst signal is inverted by multiplier 91 in every one horizontal scanning period. The resulting signal is multiplied by multiplier 92 by a chrominance subcarrier wave from terminal 10 and the output of the multiplication appears at terminal 12. Assuming that this signal keeps correct state, in case of the phase shifting by 180 deg. from this, it is in a wrong state. The color burst signal can, therefore, be discriminated. Simultaneously, the amplitude is utilized for achromatic operation. Further, the phase is adjusted easily.
