ABSTRACT:
In a digital chrominance signal processing circuit for a chrominance signal which is sampled at a frequency equal to a number of times the chrominance subcarrier frequency, this frequency can be made variable, without switching to a different crystal frequency, by using a clock signal produced by a crystal oscillator (65) and a digital oscillator (71) which is controlled via a digital number (at 73) and whose quiescent frequency can be changed by changing a number to be applied to an input (95) of an adder circuit (85). Additionally, the adder circuit (85) is supplied with a number representing a control signal (at 88) and applies via its output (83) the frequency-determining digital number to an input (73) of the digital oscillator (71).
