A method for extracting, after data collection (DC) of a sampled analog signal (x(k)), a logical description of the signal by identification of the state (A, phi ) of the signal, that is, the amplitude and phase of the signal, as well as an event ( DELTA A, DELTA phi , k=h) which causes a change of a state at a sample k=h, that the identification (SE) is performed with the aid of a truncated general Fourier series with an exponentially decreasing constant, and that the identified parameters are supplied as input data to an expert system (ES) for forming the basis of a superordinate fault analysis together with binary data originating from other signals, the result thereof then being readable on a user interface (UI) (FIG. 6). ).
