Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Ausregelung von Amplitudenschwankungen zweier um 90° el. phasenverschobener Signale (uS1, uS2) und Schaltungsanordnung zur Durchführung des Verfahrens. Erfindungsgemäß wird der positive bzw. negative Amplitudenverlauf der Signale (uS1, uS2) derart auf Unterschrei­ tung einer unteren bzw. Überschreitung einer oberen Vergleichs­ spannung (∓US₋ bzw. ∓US+) überwacht, daß bei Unterschreitung bzw. Überschreitung eine Vorrichtung (20, 22) zur Veränderung einer vorbestimmten Stellgröße eines Stellgliedes (8, 10) akti­ viert wird, und werden die Signale (uS1, uS2) jeweils in Recht­ ecksignale (uRS1, uRS2) gewandelt, aus denen mittels einer Logik schaltung (24 bzw. 26) Taktimpulse (uC11 bzw. uC12) je nach Phasenfolge der Signale (uS1, uS2) an der positiven bzw. nega­ tiven Flanke der Rechtecksignale (uRS1, uRS2) generiert werden, die den vorbestimmten Verstärkungswert in Abhängigkeit des Er­ gebnisses der Amplitudenüberwachung um einen vorbestimmten Wert (LSB) ändern. Somit erhält man ein Verfahren zur Ausregelung von Amplitudenschwankungen zweier um 90° el. phasenverschobe­ ner, alternierender, periodischer Signale (uS1, uS2) beliebiger Phasenfolge und eine Schaltungsanordnung zur Durchführung des Verfahrens, das frequenzunabhängig arbeitet.
