Procedure and device for sampling a reactance

摘要

The method involves exciting a reactance (10) by a pulse-controlled generator (12), using an electric voltage, an electric current or an electric charge. A pulse-controlled evaluator (14) produces an output signal as a function of the reactance, from discrete time scanning. The generator and evaluator are controlled in the same pulse. The pulse control of the generator and evaluator is varied in the same manner by frequency or phase modulation.
