Abstract

Interpolateur, pour l'interpolation par un rapport n de la fréquence d'échantillonnage d'un signal dit signal d'entrée, l'interpolateur étant caractérisé en ce qu'il comprend : -un premier étage d'interpolation (101) comprenant un sur-échantillonneur configuré pour sur-échantillonner le signal d'entrée d'un rapport n1, n1 étant un sous-multiple de n, et un filtre pour filtrer le signal sur-échantillonné, et - un deuxième étage d'interpolation (102) comprenant un interpolateur linéaire configuré pour interpoler d'un rapport n2 le signal issu du premier étage d'interpolation, n2 étant un sous-multiple de n. Selon un mode de réalisation, l'interpolateur comprend un troisième étage d'interpolation (103) comprenant un interpolateur bloqueur configuré pour interpoler d'un rapport n3 le signal issu du deuxième étage d'interpolation, n3 étant un sous-multiple de n. Procédé d'interpolation associé, et procédé de dimensionnement d'un interpolateur à rang élevé.
