Abstract

CIRCUIT POUR LA MULTIPLICATION D'UN NOMBRE BINAIRE PAR UN FACTEUR AJUSTABLE DE FACON ANALOGIQUE, EN PARTICULIER POUR PRENDRE EN COMPTE DES PARAMETRES AJUSTABLES, DANS LA MESURE OU LE TEST DE PROPRIETES DE MATIERES AU MOYEN D'ULTRASONS. SELON L'INVENTION, CE CIRCUIT EST CARACTERISE EN CE QU'UN DECOMPTEUR NUMERIQUE, UN COMPTEUR NUMERIQUE, UN GENERATEUR D'IMPULSIONS D'HORLOGE ET UN GENERATEUR D'IMPULSIONS AVEC UNE FREQUENCE D'IMPULSIONS VARIABLE SONT RELIES ELECTRIQUEMENT DE MANIERE QUE, LORSQUE LE NOMBRE BINAIRE QUI DOIT ETRE MULTIPLIE PAR UN FACTEUR APPARAIT A L'ENTREE DU DECOMPTEUR, CELUI-CI EST AJUSTE A CE NOMBRE, LA SORTIE D'UN ETAGE DE MISE EN MARCHE AINSI QUE LA SORTIE DU GENERATEUR D'HORLOGE ETANT TOUJOURS RELIEES A UNE ENTREE DU DECOMPTEUR. TECHNIQUE D'EXAMEN NON DESTRUCTIF PAR ULTRASONS.CIRCUIT FOR THE MULTIPLICATION OF A BINARY NUMBER BY AN ANALOGALLY ADJUSTABLE FACTOR, IN PARTICULAR TO TAKE INTO ACCOUNT ADJUSTABLE PARAMETERS, IN THE MEASURE OR TEST OF MATERIAL PROPERTIES BY MEANS OF ULTRASONICS. ACCORDING TO THE INVENTION, THIS CIRCUIT IS CHARACTERIZED IN THAT A DIGITAL DECOUNTER, A DIGITAL COUNTER, A CLOCK PULSE GENERATOR AND A PULSE GENERATOR WITH A VARIABLE PULSE FREQUENCY ARE ELECTRICALLY CONNECTED IN SUCH AS, WHEN THE BINARY NUMBER WHICH MUST BE MULTIPLIED BY A FACTOR APPEARS AT THE INPUT OF THE DECOUNTER, THIS IS ADJUSTED TO THIS NUMBER, THE OUTPUT OF A STARTING STAGE AS WELL AS THE OUTPUT OF THE CLOCK GENERATOR IS ALWAYS CONNECTED TO AN ENTRY OF THE DECOUNTER. NON-DESTRUCTIVE ULTRASONIC EXAMINATION TECHNIQUE.
