Abstract

Procédé et appareils dans lesquels un signal informationnel est converti entre des formes analogiques et numérique en deux étapes. Pour la conversion A/N, un signal analogique est converti en un mot de n + m bits dans un code special unique pour le convertisseur et ce mot est traduit en un mot de n bits dans un code binaire; pour la conversion N/A, un mot de n bits dans un code binaire est traduit en un mot de n + m bits dans le code spécial et de mot de n + m bits est converti en un signal analogique correspondant par un convertisseur unique pour le code sp cial. Procédé et appareils applicables à la réalisation de convertisseurs A/N et N/A ayant des composants à larges tolérances.
