Abstract

A configuration for the transmission of signals includes a data processing device and a functional unit, which are connected to a first and second bus system, respectively, for the respective transmission of signals with different frequencies. A transmission unit is connected to the data processing device through the first bus system and to the functional unit through the second bus system, for the transmission and conversion of signals between the data processing device and the functional unit. It additionally serves for the electrical decoupling of the first bus system and the second bus system. As a result, independently of the electrical properties of the functional unit, a high data throughput is made possible in conjunction with still good detectability of the signals to be transmitted.
