Abstract

PROCEDE POUR LA MULTIPLICATION D'UNE VALEUR STOCHASTIQUE AU PLUS EGALE A 0,5, PAR UN NOMBRE 1 K, AVEC 0 K 1, VALEUR STOCHASTIQUE QUI SE TROUVE PHYSIQUEMENT REPRESENTEE PAR UNE SEQUENCE DE NIVEAUX LOGIQUES 0 ET 1, TELLE QUE DANS CERTAIN INTERVALLE DE TEMPS, IL APPARAIT N NIVEAUX LOGIQUES 1. SELON L'INVENTION, CE PROCEDE EST CARACTERISE EN CE QUE, A PARTIR DE LADITE SEQUENCE ON FORME UNE PREMIERE SEQUENCE AUXILIAIRE COMPORTANT KN NIVEAUX LOGIQUES 1, PUIS UNE SECONDE SEQUENCE AUXILIAIRE COMPORTANT N NIVEAUX LOGIQUES 1, CHAQUE NIVEAU LOGIQUE 1 DE CHACUNE DES DEUX SEQUENCES AUXILIAIRES ETANT D'UNE PART, DEDUIT D'UN NIVEAU LOGIQUE 1 DE LA SEQUENCE INITIALE ET D'AUTRE PART TEMPORELLEMENT EN REGARD D'UN NIVEAU ZERO DE L'AUTRE SEQUENCE AUXILIAIRE, APRES QUOI LESDITES SEQUENCES AUXILIAIRES SONT AJOUTEES L'UNE A L'AUTRE. TRAITEMENT STOCHASTIQUE DE L'INFORMATION.
