    • Disclosed are a subscriber station (10) for a bus system, preferably a LIN bus system, and a method for adjusting the timing of a transmit signal for a bus system. The subscriber station comprises a first detection unit (131) for detecting a measure of the emission/radiation caused by switching processes taking place because a message is sent within the bus system, a second detection unit (132) for detecting the steepness of the edge of a message sent within the bus system, and an adjustment device (133) for adjusting the steepness and/or the shape of the edge of the message sent within the bus system on the basis of a result detected by the first detection unit (131) and a result detected by the second detection unit (132) in order to minimize interferences caused by switching processes taking place because a message is sent within the bus system and in order to meet the requirements of the bus system in respect of the timing of the message.

    • The invention provides a subscriber station (10; 30) for a bus system (1) and method for improving the quality of transmission in a bus system (1). The subscriber station (10; 30) comprises a transmission/reception device (12) for transmitting or receiving a message (45; 46; 47) to/from at least one further subscriber station of the bus system (1) via the bus system (1), in which bus system (1) is ensured at least intermittently an exclusive, collision-free access of a subscriber station (10, 20, 30) to a bus (40) of the bus system (1), wherein the transmission/reception device (12) comprises a transmission signal processing device (123) for transmission signal processing of a transmission signal to be transmitted by the transmission/reception device (12), and wherein the transmission signal processing unit (123) is designed for adjusting a predetermined bit symmetry of bits of the transmission signal by generating an internal transmission signal for the message (45; 46; 47), wherein the dominant phase of the bits is shortened and the recessive phase of the bits is extended, in the internal transmission signal.
