Système d'aide à l'analyse spectrale : communication entre un logiciel de traitement du signal graphique et un système expert

Abstract : This paper presents a part of a help system for spectral analysis. The final objective consists in helping an user to choose an adequate method with adapted parameters as also to realize a spectrum interpretation the more comprehensive with regard to the application domain and the analysis method. It follows three constraints: a knowledge based on recent techniques, an autonomous interpretation of the estimated spectrum and a strong interaction with the user. Then it was necessary on the one hand to realize a communication interface between the graphic software, on which a consequent number of spectral analysis methods is implemented, and an expert system generator, in the other hand to convert the estimated spectrum into symbols comprehensive by th expert system.
