摘要： A two-wire bus system for connecting a plurality of users has at least one damping circuit for damping line resonances in the two-wire bus system with respect to a reference potential. The damping characteristic of the damping circuit is selected such that the damping only becomes operative above a preestablished reference voltage threshold1 value. In this manner, it is achieved that a useful signal is not weakened by the damping circuit, but rather resonance voltages are damped only above the threshold value. It is advantageous if each of the users of the bus system has assigned to it a damping circuit.
