ABSTRACT:
A circuit arrangement for deriving a control signal from a synchronizing signal whose phase alternates in a predetermined sequence, which control signal is independent of the phase alternation, comprises a reference oscillator (1) which supplies a reference signal, a phase comparator (5) for deriving a phase signal from a synchronizing signal and a reference signal, a correction circuit (22, 26) for generating a correction signal, and a logic combination device (10) for superimposing the phase signal and the correction signal on the control signal. In accordance with the invention control signal variations as a result of the phase alternations in the synchronizing signal are eliminated in that the correction circuit (22, 26) generates a polarity signal which dictates the polarity of the correction signal by comparing the phase of the reference signal and the phase of the synchronizing signal.
