Abstract

L'invention concerne un synthétiseur polyphonique de signaux périodiques utilisant les techniques numériques. L'ensemble des données qui caractérisent chaque échantillon de chaque signal périodique est défini dans des blocs de mémoires inclus dans des groupes associés à autant de circuits générateurs de signaux rectangulaires. Une mémoire supplémentaire par groupe contient en outre un sous-multiple commun de la phase instantanée des signaux périodiques du groupe. Les opérations de lecture, de calcul et de conversion se font selon un enchaînement prédéterminé, d'après le contenu des mémoires. Applications aux instruments de musiques.
