ABSTRACT:
A signal preprocessing device is disclosed, which is integrated into a structure-borne sound sensor or into an acceleration sensor for sensing structure-borne sound, or which is connected at the input end to at least one sensor of this type and is connected at the output end to at least one signal channel that is connected to at least one central electronic control unit, and wherein the signal preprocessing device has at least one filter module having at least two bandpass filters.A method for preprocessing structure-borne sound sensor signals is also disclosed, in which a filtering operation is carried out in which at least two frequency bands, which are at least to a certain extent part of the structure-borne sound spectrum, are transmitted. Use of the above device in electronic motor vehicle security systems, in particular safety systems, in particular in vehicle occupant protection systems and/or passenger protection systems is also disclosed.
