The invention relates to a method of capacitive measurement between an object and an electrode plane, in which method use is made of a processing unit so as to: - apply an excitation signal to the resistive electrode plane, and - determine a value of capacitance on the basis of a measurement of a measurement signal originating from the electrode plane. According to the invention the excitation signal is a nonsinusoidal signal comprising at least one discontinuity, and to determine the value of capacitance, the measurement signal is attenuated over a time window, this time window being the duration for which the resistivity of the electrode plane is manifested on the measurement signal in response to said at least one discontinuity. |
