Abstract

Die Erfindung betrifft analoge Schaltungsanordnungen zum Erzeugen von Ausgangssignalen, deren Kurvenverlauf wenigstens abschnittsweise einer elliptischen Funktion entspricht oder angenähert ist. Hierzu werden vorzugsweise analoge Standardbausteine, wie Addierer, Integrier, Multiplizier und Differenzverstärken zusammengeschaltet, um elliptische Zeitfunktionen schaltungstechnisch nachzubilden.
