Abstract

L'invention se réfère à un générateur numérique d'ondes sinusoïdales échantillonnées, ce générateur comportant des moyens d'addition et de multiplication pour exécuter l'algorithme général suivant : Ak+1 = aAk - bBk, Bk+1 - bAk + aBk , l'onde sinusoïdale étant définie à l'instant k par la somme Ak + jBk = Rel **k phi . Selon l'invention, on effectue une correction des valeurs selon un algorithme particulier pour tenir compte des erreurs de troncature et d'imprécision calcul. L'invention est applicable aux moyens de modulation et de démodulation numérique concernant un signal MIC.
