Abstract
A transmitting/receiving device for a bus system and a method for reducing an oscillation tendency in the case of coupled-in interferences, in particular, in the transition between different bus states. The transmitting/receiving device has a transmitting stage for transmitting a transmit signal to a first bus wire of a bus of the bus system, and for transmitting the transmit signal to a second bus wire of the bus, and an oscillation reduction module for damping an oscillation of a bus signal arising at terminals for the bus wires when the transmitting/receiving device acts as the transmitter of the transmit signal. The oscillation reduction module includes a first resistor, which is switchable between the first bus wire and a terminal for ground, and the oscillation reduction module including a second resistor, which is switchable between the second bus wire and a terminal for a voltage supply of the bus system.
