Abstract
A color signal demodulating device designed so that a local subcarrier oscillator generates a demodulating signal which is both synchronized and inverted in phase with respect to a color signal at each horizontal scanning period so as to demodulate an R-Y signal and which reverses phase with each horizontal scanning period; a bust signal and a signal inverted in phase therefrom are alternately switched therebetween and used to drive the local subcarrier oscillator. The output of this local subcarrier oscillator can be used for both the demodulation signal for the R-Y carrier and as the demodulation signal for the B-Y demodulator.
