Abstract

SYSTEME DE TRANSMISSION SEQUENTIELLE AUTO-RYTHMEE DE DONNEES BINAIRES DU GENRE OU DES BITS DES DEUX ETATS SONT NORMALEMENT TRANSMIS SOUS FORME DE TRANSITIONS, SOIT AVANCEES, SOIT TARDIVES, DANS CES CELLULES RESPECTIVES, AVEC SUPPRESSION DE TOUTE TRANSITION AVANCEE QUI DEVRAIT INTERVENIR A LA SUITE D'UNE TRANSITION TARDIVE. UN MOYEN MODIFICATEUR DE TRANSITION EST ASSERVI A UN COMPTEUR DES SEQUENCES DE BITS D'UN PREMIER ETAT POUR INTERVENIR EN FONCTION, NOTAMMENT DE LA PARITE DU COMPTAGE, ET UN MOYEN DE PREVISION LIMITE SENSIBLE A UN NOMBRE LIMITE DE BITS SUIVANTS EST ADAPTE A RENDRE INOPERANT LEDIT MOYEN MODIFICATEUR LORSQUE LA PREVISION ETABLIT QUE L'ON PEUT SANS INCONVENIENT SE PASSER DE SON INTERVENTION. APPLICATION AUX CANAUX DE TRANSMISSION COMPORTANT UN ENREGISTREUR DE BANDE.AUTO-Paced SEQUENTIAL TRANSMISSION OF GENDER BINARY DATA OR BITS FROM BOTH STATES ARE NORMALLY TRANSMITTED IN THE FORM OF TRANSITIONS, EITHER ADVANCED, OR LATE, IN THESE RESPECTIVE CELLS, WITH THE DELETION OF ANY ADVANCED TRANSITION THAT SHOULD FOLLOWING THEREFORE 'A LATE TRANSITION. A TRANSITION MODIFIER MEANS IS SLOWED TO A COUNTER OF THE SEQUENCES OF BITS OF A FIRST STATE TO ACT AS A FUNCTION, IN PARTICULAR OF THE PARITY OF THE COUNTING, AND A MEANS OF FORECASTING LIMITED SENSITIVE TO A LIMITED NUMBER OF FOLLOWING BITS IS SUITABLE TO RENDER INOPERABLE THESE MODIFIER MEANS WHEN THE FORECAST ESTABLISHES THAT IT CAN BE GIVEN WITHOUT INCONVENIENCE. APPLICATION TO TRANSMISSION CHANNELS INCLUDING A BAND RECORDER.
