摘要

Electrical circuit (10) for processing a voltageless electric signal generated from an inductive sensor, e.g. within a combustion engine. The signal is transmitted over two leads (21, 22) to the input of a first comparator (23). The latter has one input connected to one of the leads and the other to a threshold value. The circuit also comprises a peak value rectifier with which the threshold value input to one of the connections is adjusted.
