Abstract

Abstract Translated from German 57 Die Erfindung betrifft eine Phasenvergleichsschaltung zur Ermittlung der Phasenverschiebung zwischen einem Eingangs- und Referenzsignal. Das Eingangssignal wird während zweier aufeinanderfolgender definierter Integrationsintervalle, die aus dem Referenzsignal abgeleitet werden, integriert. Die Integralwerte, die den Integrationsintervallen zugeordnet sind, werden gewichtet und es wird die Differenz gebildet. Vom Ergebnis dieser Differenzbildung wird das Ausgangssignal der Phasenvergleichsschaltung abgeleitet. 57 The invention relates to a phase comparison circuit for determining the phase shift between an input and reference signal. The input signal is integrated during two successive defined integration intervals which are derived from the reference signal. The integral values assigned to the integration intervals are weighted and the difference is formed. The output signal of the phase comparison circuit is derived from the result of this difference formation.
