Method for analysing and evaluating signal, particularly sensor signal, involves carrying out frequency analysis of unfiltered signal for determining frequency spectrum

摘要

The method involves carrying out a frequency analysis of an unfiltered signal (S2) for determining a frequency spectrum. A frequeny portion in the determined frequency spectrum is evaluated (S3) for determining a close spectral signal power. The determined close spectral signal power is set (S4) relative to a filtered signal. Independent claims are also included for the following: (1) a device for analysing and evaluating signal (2) a controller for a passenger protective system of a vehicle.
