Abstract

In a data communication system, in particular for a motor vehicle, the transmission lines that lead to the individual terminals are interconnected at a passive network in a star configuration and are there provided with frequency-dependent attenuation means, preferably ferrite beads. Good characteristic impedance adaptation is thus obtained for suppressing high-frequency distributing signals, while retaining free choice of the system parameters for the steady data symbolic state. The system may be enlarged by means of additional star networks into a tree or meshed structure.
