The invention concerns a method for the automatic analysis of frequency passband of recorded signals, characterised in that it consists in: a) applying a Fourier transform on at least one of the signals to obtain an amplitude spectrum of said signal; b) producing a mean spectrum of said amplitude spectrum; c) analysing said mean spectrum so as to produce a spectral component representing said signal; d) determining, on the basis of the representative spectral component, the minimum (F¿min?) and maximum (F¿max?) frequency values for which the amplitude of said spectral component is equal to half (A¿max?/2) of the maximum amplitude (A¿max?). The invention is particularly useful for determining the passband of seismic signals.
Méthode d'analyse automatique de bande passante fréquentielle de signaux enregistrés. La méthode est caractérisée en ce que'elle consiste à: a) appliquer une transformée de Fourier sur au moins un des signaux, de manière à obtenir un spectre d'amplitude dudit signal; b) réaliser un spectre moyen dudit spectre d'amplitude; c) analyser ledit spectre moyen, de manière à produire une composante spectrale représentative dudit signal; et d) déterminer, à partir de la composante spectrale représentative, les valeurs de fréquence minimale (Fmin) et maximale (Fmax) pour lesquelles l'amplitude de ladite composante spectrale est égale à la moitié (Amax/2) de l'amplitude maximum (Amax). Application notamment à la détermination de la bande passante de signaux sismiques.
