Abstract
A digital signal processing circuit, for example, a digital signal adder circuit suitable for use in a digital color encoder for generating a digital composite color video signal from three digital primary color signals. At least two input digital signals are respectively supplied to a signal delay circuit which generates the digital signal in the form of skew bits wherein the higher bit is given a larger delay. The output signals of the signal delay circuit are supplied to an adder circuit in which the small number of bits of the digital signals are added during one clock interval. And, the output signal of the adder circuit is supplied to a further delay circuit which generates a digital signal in the form of linear bits wherein any bit in originally the same clock interval is given the same delay.
