Abstract
A transmitting/receiving device for a bus system and a method for reducing an oscillation tendency in the transition between different bit states. The transmitting/receiving device has a transmitting stage for transmitting a transmission signal to a first bus wire of a bus of the bus system and for transmitting the transmission signal as an inverse signal to a second bus wire of the bus, and an asymmetry reduction module for reducing an asymmetry of bus signals arising in the bus wires. The asymmetry reduction module includes a polarity reversing diode, whose cathode is connected to the cathode of a reverse polarity diode of the transmitting stage. The asymmetry reduction module switches a potential of the cathode of the polarity reversing diode to a potential that is greater than or equal to a level of a recessive bus state.
