Abstract

Zur Demodulation eines amplitudenmodulierten Signals sind zwei Kondensatoren (C1, C2) vorgesehen, denen ein mit einer Diode (D1) gleichgerichtetes Signal mit einer Spannung (U1) zuführbar ist. Die Halbwellen dieses Signals werden mit einem Schalter (S3) abwechselnd zur Aufladung des ersten oder zweiten Kondensators benutzt. Mit Schaltern (S1, S2) werden die Kondensatoren (C1, C2) entladen. Ein Vergleich der in den Kondensatoren (C1, C2) gespeicherten Amplitudenwerte aufeinanderfolgender Halbwellen in einer Auswerteeinheit (AE) ermöglicht eine einfache, mit wenigen Bauelementen realisierbare und präzise Demodulation, welche bei sehr hohen Frequenzen möglich ist.
