Abstract
An absorber unit is disclosed for increasing the noise immunity of a system bus. In order to improve the noise immunity of the system bus, the system bus is designed such that communication can take place in a defined communication frequency spectrum. In at least one embodiment, the absorber unit includes a high-pass filter and an absorber resistor. The high-pass filter can be connected to the system bus on the input side and to the absorber resistor on the output side and is dimensioned such that is has a low-impedance effect for noise signals above the communication frequency spectrum so that those signals are absorbed by the absorber resistor.
