METHOD FOR FORMING THE EDGES OF SIGNALS AND EMITTER/RECEIVER MODULE FOR A BUS SYSTEM

摘要

The invention relates to a method for forming the edges of signals, and to an emitter/receiver module for a bus system. Said emitter/receiver module (TR) for a bus system comprises a driver transistor (T1) which is looped in between a bus line (BL) of the bus system and a reference potential (GND) and is used for outputting signals (UBL) on the bus line (BL), a control unit (AE) for the driver transistor (T1), and a high-frequency interference detector (HFD) which is embodied in such a way that it determines a high-frequency interference level on the bus line (BL) of the bus system. The control unit (AE) is embodied in such a way that it controls the driver transistor (T1) according to the determined high-frequency interference level, such that an edge steepness of the outputted signals (UBL) increases when the high-frequency interference level on the bus line (BL) increases, and an edge steepness of the outputted signals (UBL) decreases when the high-frequency interference level on the bus line (BL) decreases. The invention can be used for example for bus systems.
