A number of charges flowing to the capacitor 35b form a voltage integral 14b across the induced voltage. The voltage value of the capacitor 35b, which can be determined by means of the control unit 10b, is proportional to the number of charges that have flowed. The voltage value thus directly forms a parameter by means of which the voltage integral 14b can be determined.
