Abstract

Abstract Translated from German Zum Synchronisieren eines spannungsgesteuerten Oszillators (1) sind eine Meßeinrichtung (2,3,4) und eine durch diese gesteuerte Steuereinrichtung (6,7) vorgesehen. Die Meßeinrichtung stellt die Phasenabweichung der von dem Oszillator (1) erzeugten Taktimpulse zu externen Taktimpulsen unterschiedlicher Frequenz fest. Als Steuereinrichtung dient insbesondere ein Mikroprozessor bzw. Mikrocomputer (6). A measuring device (2, 3, 4) and a control device (6, 7) controlled by this are provided for synchronizing a voltage-controlled oscillator (1). The measuring device determines the phase deviation of the clock pulses generated by the oscillator (1) from external clock pulses of different frequencies. A microprocessor or microcomputer (6) is used in particular as the control device.
