Abstract

The method involves producing two measuring signals, which are out of phase with one another, where the measuring signals are supplied to transmission electrodes. Received signal is evaluated at a measuring electrode and is supplied to an evaluation unit, which determines the partial capacitance between the transmission electrodes and the measuring electrode proportional values. The transmission electrodes are simultaneously controlled with transmission signals (S1, S2).
