Abstract
An attenuating device for a bus of a controller area network bus system based on differential voltage signals. The bus has first and second bus lines, having an attenuating circuit that provides a variable electrical resistance value between the first and second bus lines and that is operable in at least three circuit states. In a first circuit state, the first and second bus lines are connected via an attenuating resistor having a first resistance value. In a second circuit state, the first and second bus lines are connected via an attenuating resistor having a second resistance value. In a third circuit state, the first and second bus lines are connected via an attenuating resistor having a third resistance value. The first resistance value is lower than the second resistance value. The second resistance value is lower than the third resistance value.
