ABSTRACT:
Method for filtering the luminance signal from a CCVS television signal, which includes sampling the CCVS signal in a CTD filter with twice the color carrier frequency, converting the CCVS signal into a charge packet proportional to its voltage, dividing the charge packet into first and second charge parts in a ratio of 1:1, conducting the first and second charge parts through separate branches, delaying the first charge part relative to the second charge part by one given sampling period in the branches, and subsequently recombining the charge parts in an output channel, and an apparatus for carrying out the method.
