ABSTRACT:
For evaluating the essentially-periodic signal sequence of inductive measured-value sensors in view of the appearance of zero-axis crossings, all zero-axis crossings in the sensor signal are identified in a zero-axis crossing branch of an evaluation unit and the significant zero-axis crossings are enabled in a parallel enable branch after logarithmic transformation of the sensor signal.
