Abstract

Abstract Translated from German Einen mit wenigen Frequenzen auskommendes, einfach aufgebautes System zur Informationsübertragung, welches aus einer Abfrageeinheit (AF) und einer Antworteinheit (AW) besteht, wird eine enziges von der Abfrageeinheit (AZ) ausgesendetes Trägersignal (fp) einem parametrischen Frequenzumsetzer (PU) in der Antworteinheit (AW) zugeführt und eine vom Umsetzer (PU) abgegebene Schwingung (f H ) nach Modulation mit der in der Antworteinheit abgespeicherten Information (m) zur Abfrageeinheit (AF) zurückgesendet und dort demoduliert. A system of information transmission that manages with few frequencies and consists of a query unit (AF) and a response unit (AW) becomes a unique carrier signal (fp) transmitted by the query unit (AZ) to a parametric frequency converter (PU) in the response unit (AW) and a vibration (f H ) emitted by the converter (PU) after modulation with the information (m) stored in the response unit is sent back to the interrogation unit (AF) and demodulated there.
