Abstract
A method and circuit for transmitting a data-modulated high-frequency data signal ffrom a transmitter to a receiver, for transmitting data between a read-write device (RWD) and at least one mobile data memory (MDM) in an identification system that has a number of mobile data memories (MDM) which are placed on objects and which are provided for detecting object-specific status data and/or process data. Such an identification system is particularly useful, e.g., in a shipping, transport and/or manufacturing system of the individual objects. In addition to the transmitted high frequency data signal f, a further high-frequency data signal fis transmitted, which serves to convert the frequency and/or to modulate the carrier code of the high-frequency data signal f.
