Abstract

Son unité de base comprend deux circuits multiplicateurs, un circuit additionneur et un circuit soustracteur, en une combinaison logique de commutation définie. Peut encore comporter éventuellement deux circuits à action proportionnelle. Permet de déterminer les deux coordonnées cartésiennes a1, a2. Si le module a est constant, le convertisseur peut servir de générateur de sinus-cosinus. Il comprend aussi une unité complémentaire pour la formation d'un vecteur tournant
