Abstract

Schaltungsanordnung zur Parametereinstellung mit mindestens einer ersten analogen Multipliziereinrichtung (1, 2, 3), der ein Eingangssignal (17, 18, 19) sowie ein einem Parameter entsprechendes Steuersignal zugeführt wird und die ein Ausgangssignal (20, 21, 22) abgibt,
mit einer zur ersten Multiplikationseinrichtung (1, 2, 3) identischen zweiten Multiplikationseinrichtung (25), der ein erstes Referenzsignal sowie ein dem ersten Steuersignal entsprechendes zweites Steuersignal zugeführt werden und die ein Ausgangssignal (Ui) abgibt, und mit einer Regeleinrichtung (38 bis 45), die das Ausgangssignal (Ui) der zweiten Multipliziereinrichtung (25) mit einem zweiten Referenzsignal (Us) vergleicht und daraus die Steuersignale ableitet.
