METHOD FOR PROCESSING A SIGNAL COMPRISING A DETECTION OF PERTURBATIONS CAUSED BY A FACTOR IMPACT

摘要

Method for processing a signal by means of an electronic control unit on board an aircraft, wherein the electronic control unit receives an input signal (S01) comprising useful data in a first passband, implements a first operation (S04) of bandpass filtering the input signal with a first passband to obtain a useful signal containing the useful data, with detection of interference caused by a lightning strike comprising: - a second operation (S05) of bandpass filtering the input signal to obtain a detection signal, the bandpass filter having a second passband that is distinct from the first passband; - comparing (S07) a detection value derived from the detection signal with a detection threshold, and correcting (S08) the exploitation (S09) of the useful data if exceeded.
