ABSTRACT:
Method for processing a sensor signal of a knocking sensor for an internal combustion engine, having the following steps: a time window is defined for the evaluation of the sensor signal as a function of the operating state and/or the operating behavior of the internal combustion engine, a plurality of sampled values of the sensor signal are sampled within the predefined time window with a predefined sampling frequency, and an output signal which represents the knocking behavior of the internal combustion engine is determined from the sampled values, the Fourier transform of the sampled values being calculated in order to determine the output signal.
