Abstract

a. Dispositif pour convertir un signal échantillonné de façon non uniforme avec un spectre de courte durée en un signal échantillonné de façon uniforme. b. Dispositif caractérisé en ce qu'il comprend une chaîne à retard, une unité de multiplication, un circuit de sommation, un analyseur d'onde, une unité logique, permettant ainsi d'extrapoler par établissement de séries de Fourier, les échantillons manquant dans le signal échantillonné de façon non uniforme pour le transformer en un signal échantilloné de façon uniforme. c. L'invention s'applique notamment à la transmission des signaux de conversations téléphoniques.
