Abstract
The measuring accuracy and the signal-to-fault voltage ratio of a circuit configuration and a process for measuring a variable that influences the capacitance curve as a factor of voltage of a capacitive element is improved by calculating the variable from the area below the capacitince curve as a factor of voltage.
