Abstract of the Disclosure A signal separator includes an A/D converter which samples a composite color television signal including a luminance signal component and a color difference signal component at a sampling frequency four times a frequency of a chrominance subcarrier and outputs a digital signal. A timing signal generator receives the digital signal and generates at least first and second timing signals. A subsampling circuit subsamples the digital signal in accordance with the first timing signal and outputs a subsampled signal. A frame delaying circuit delays the subsampled signal by one frame and outputs a delayed signal. The signal separator further includes first interpolation circuit which interpolates the delayed signal in accordance with the second timing signal and outputs a first interpolated signal. A first separator separates the color difference signal com- ponent from the composite color television signal by mixing the first interpolated signal and the digital signal. A second interpolation circuit interpolates the color difference signal component by a predetermined signal and outputs a second interpolated signal. A second separator separates the luminance signal compo- nent by mixing the first interpolated signal and the second interpolated signal.
