The present invention relates to a keyboard with a plurality of sensitive key elements (10, 12, 14) arranged on said keyboard according to a predetermined scheme. Each of the key elements (10, 12, 14) provides an analogue electric signal (U1, U2, U3). The analogous electric signal (U1, U2, U3) depends on the position of a fingertip. A contact surface of the key element (12) is subdivided into zones (A, B, C, D). The zones (A, B, C, D) are defined in such a way, that the zones (A, B, C, D) have different distances from the adjacent key elements (10, 14). Each zone (A, B, C, D) corresponds with a range of relationships between the signal (U2) of the key element (12) and the signal (U1, U3) of at least one adjacent key element (10, 14).

The present invention relates to a system for processing a signal (U) from an electric device (10), e.g. a touch sensitive key. The system comprises a reference value (U ref ) for the signal (U), wherein said reference value (U ref ) is continuously updated, and an arithmetic unit for determining, a difference value (ΔU) between the signal (U) and the reference value (U ref ), so that difference value (ΔU) corresponds with a change of the signal (U). The system comprises further a spectrum of the possible difference values (ΔU), wherein said spectrum is subdivided into ranges (21,23,25,27,29,31,33,35,37,39) corresponding with possible causations for the change of the signal (U) in said system. Additionally, the system comprises a comparing unit for associating the difference value (ΔU) with the corresponding range (21,23,25,27,29,31,33,35,37,39) of the spectrum and for identifying, if the difference value (ΔU) results from a disturbance or from a relevant change in the electric device (10). Further, the present invention relates to a corresponding method.
