Abstract
A device including a comparator (3) each input of which receives signals from an information transmission line (1, 2) through a capacitor (4, 5), is characterized in that devices for forced switching (6) are interposed between the information transmission lines (1, 2) and the inputs of the comparator (3), the output of the latter being connected to one input of an OR gate (7) whose other input receives a reinitialization signal from a protocol decoder and whose output is connected directly and through an inverter to the device for forced switching (6) in order to reinitialize the comparator when the latter is blocked in a dominant state following interference.
