Abstract

DISPOSITIF DE RESTITUTION D'INFORMATION RECUE SOUS FORME NUMERIQUE MIC EN CODE BIPHASE, SE PRESENTANT SOUS FORME D'UN SIGNAL AYANT DES TRANSITIONS DE PHASE D'UN PREMIER TYPE A LA FREQUENCE D'UNE HORLOGE D'EMISSION ET, DANS LES INTERVALLES ENTRE TRANSITIONS DU PREMIER TYPE, DES TRANSITIONS DE SECOND TYPE REPRESENTATIVES DE L'INFORMATION. IL COMPORTE UNE HORLOGE LOCALE 16, DES MOYENS 21, 24, 26 POUR DETERMINER PERIODIQUEMENT LE NOMBRE N DE PERIODES DE L'HORLOGE LOCALE COMPRIS ENTRE DEUX TRANSITIONS SUCCESSIVES DE PREMIER TYPE, ET DES MOYENS POUR DETECTER LES TRANSITIONS DE SECOND TYPE PENDANT DES INTERVALLES DE TEMPS CORRESPONDANT A UN NOMBRE N DE PERIODES DE L'HORLOGE LOCALE TEL QUE N2NN. APPLICATION A LA TRANSMISSION D'INFORMATIONS.DEVICE FOR RETURNING INFORMATION RECEIVED IN MIC NUMERICAL FORM IN BIP-PHASE CODE, IN THE FORM OF A SIGNAL HAVING FIRST-TYPE PHASE TRANSITIONS AT THE FREQUENCY OF A TRANSMISSION CLOCK AND, IN THE INTERVALS BETWEEN TRANSITIONS OF THE FIRST TYPE, TRANSITIONS OF THE SECOND TYPE REPRESENTATIVE OF INFORMATION. IT INCLUDES A LOCAL CLOCK 16, MEANS 21, 24, 26 FOR PERIODICALLY DETERMINING THE NUMBER N OF PERIODS OF THE LOCAL CLOCK INCLUDED BETWEEN TWO SUCCESSIVE TRANSITIONS OF THE FIRST TYPE, AND MEANS FOR DETECTING THE TRANSITIONS OF THE SECOND TYPE DURING INTERVALS OF TIME CORRESPONDING TO A NUMBER N OF PERIODS OF THE LOCAL CLOCK SUCH AS N2NN. APPLICATION TO THE TRANSMISSION OF INFORMATION.
