Abstract
Ce dispositif servant à multiplier deux nombres binaires en notation avec complément à deux comporte un montage pour former des produits partiels binaires et un autre montage pour en extraire successivement les éléments binaires de résultats Les modules du reste du montage forment soit un additionneur complet soit un soustracteur complet sbus la commande d'un signal de commande à un seul élément binaire. Ainsi, on peut tenir compte du signe négatif des éléments binaires les plus significatifs des facteurs. Ce dispositif peut être avantageusement réalisé en logique << quatre phases >>. Application aux calculatrices.
