Abstract
An evaluating circuit for an inductive pickup has a rectangular signal generator for outputing a rectangular signal, a driver stage for supplying a displaement pickup with an input signal produced from the rectangular signal, a phase-coupled rectifier operative for rectifying an output signal of the displacement pickup with consideration of a phase of the rectangular signal, a sweeping/holding circuit for sweeping the rectified output signal in established sweeping time intervals, and a pulse supplying circuit which at predetermined time points produced on flanks of the rectangular signal control pulses for establishing the sweeping time intervals. The predetermined time points are selected so that during the sweeping time intervals established by the time points the output signal after introducing of rectangular pulse in the displacement pickup is substantially naturally oscillated.
