Device for evaluating periodic signals from inductive pick-ups having a pulse former stage influenced as a function of the pick-up signal amplitude

A device for evaluating periodic signals from inductive pick-ups compensates for the lag of the pick-up signal. This lag increases with increasing frequency as a consequence of the inductance of the pick-up, with respect to the position of a movable part that is to be scanned by the said pick-up. Th...

Summary:A device for evaluating periodic signals from inductive pick-ups compensates for the lag of the pick-up signal. This lag increases with increasing frequency as a consequence of the inductance of the pick-up, with respect to the position of a movable part that is to be scanned by the said pick-up. The relative time shift in the evaluation edge of the pick-up signal, which is phase-compensated via the frequency, is compensated for via changes in the amplitude of the pick-up signal.
