ABSTRACT:
To process the output signal of a rotational speed sensor (2) which generates an alternating voltage dependent in respect of frequency and amplitude on the rotational speed, two low-pass filters (TP1, TP2) serve to produce a useful signal (I1), on the one hand, and a reference signal (I2), on the other hand. The two signals are compared. In dependence on the difference of these signals (I1, I2) a pulse-shaped output signal, namely the processed sensor signal, is generated by means of a comparator (7). The reference signal dynamically follows the useful signal with the aid of a control signal issue by an adapter circuit (20,21).
