In order to evaluate and process measuring signals of a capacitive differential transducer (1), it is proposed to operate two oppositely controlling RC oscillators in a closed circuit. The time determining partial capacitor (5 or 6) of the differential measurement transducer (1) is switched against a shared reference potential (7) and, after the antivalency interfacing of the partial signals e1 and e2, one partial capacitor determines the "high" time and the other the "low" time of a pulse-width-modulated output signal (14) of this circuit (15).
