Abstract

PURPOSE: To prevent an interference between a wide band luminance signal and a chrominance signal, without spoiling the band of a luminance signal by providing the transmission route of the luminance signal with the separating means of the signal component of the frequency band of a carrier chrominance signal, and one horizontal interdigital filter.
CONSTITUTION: When the luminance signal Y having a wide spectrum A up to a frequency larger than a chrominance carrier frequency fsc is inputted to an input terminal 1, the signal component, the center of which is fsc and which has the same frequency spectrum as the frequency spectrum B of the carrier chrominance signal C, is separated by a band pass filter 12. A subtracter 13 subtracts the said signal component (spectrum B) from the input luminance signal (spectrum A). The output of the filter 12 comes to be a band limited interdigital spectrum through the interdigital filter 20, consisting of a 1H delay line 21 and an adder 22, and a counter 25, and is added together with the partial missing spectrum C of the output of the subtracter 13, and comes to be a partial spectrum E. The signal E is added together with the carrier chrominance signal C from the input terminal 2 by the adder 3, and outputted from an output terminal 4.
