Verfahren und Schaltung zur Übertragung eines datenmodulierten Hochfrequenz-Datensignals von einem Sender zu einem Empfänger mit vereinfachter Empfängerarchitektur

摘要

The invention relates to a method and circuit for transmitting a data-modulated high-frequency data signal fC from a transmitter to a receiver, especially for transmitting data between a read-write device (SLG) and at least one mobile data memory (MDS) in an identification system comprising a number of mobile data memories (MDS) which are placed on objects and which are provided for detecting object-specific status data and/or process data e.g. in a shipping, transport and/or manufacturing system of the individual objects, whereby, in addition to the transmitted high frequency data signal fC, a high-frequency data signal fS is transmitted, which serves to convert the frequency and/or to modulate the carrier code of the high-frequency data signal fC.
