Abstract
An impact sensor, or a method for testing the impact sensor. The impact sensor has a sensor element and a filter for filtering the signals of the sensor element. This filter is preferably a low-pass filter. Using a test signal, the filter is tested, and if there is a deviation the filter is corrected using a software filter or through a parametrization of the triggering algorithm.
