Abstract

L'invention concerne un synthétiseur polyphonique de signaux périodiques. Les fréquences des signaux périodiques situés dans l'octave basse sont définies par un ensemble de signaux impulsionnels. Les amplitudes de tous les signaux périodiques sont définies par des données numériques des mémoires Chaque impulsion déclenche des lectures de données numériques successives dans les mémoires et des conversions de ces données en échelons de tension ou de courant analogique d'amplitudes proportionnelles aux données. Applications aux instruments de musique électroniques.
