Abstract

Procédé de numérisation, numériseur et plate-forme associés La présente invention concerne un procédé de numérisation d’un signal (s(t)), dit signal à numériser, le procédé comportant au moins une étape de : - sélection d’une fréquence d’une partie du signal, une fréquence étant sélectionnée lorsqu’à la fréquence considérée, l’amplitude de la partie de signal est maximale en valeur absolue, - étalement spectral de la partie de signal selon une technique utilisant ladite au moins une fréquence sélectionnée pour obtenir une partie de signal étalée, - numérisation d’un signal obtenu à partir du signal étalé par un convertisseur analogique-numérique (30), pour obtenir un signal numérisé étalé, et - recombinaison du signal numérisé étalé. Figure pour l'abrégé : Figure 2The present invention relates to a method for digitizing a signal (s (t)), called the signal to be digitized, the method comprising at least one step of: selecting a frequency d 'a part of the signal, a frequency being selected when, at the frequency considered, the amplitude of the part of the signal is maximum in absolute value, - spectral spreading of the part of the signal according to a technique using said at least one frequency selected for obtaining a portion of the spread signal, - digitization of a signal obtained from the spread signal by an analog-to-digital converter (30), to obtain a digitized spread signal, and - recombination of the digitized spread signal.
