Abstract

La présente invention concerne l'amplification de signaux transmis en code ternaire sortant d'un dispositif de régénération Le dispositif de l'invention comporte un interrupteur pour les impulsions positives (resp. négatives) constitué de deux transistors T1 et T 2 ayant leurs bases reliées aux bornes d'entrée et leurs émetteurs réunis entre eux, leurs collecteurs étant reliés aux émetteurs de deux autres transistors T3 et T4 respectivement, les bases desdits transistors T3 et T4 étant portées à la masse et les collecteurs réunis d'une part à des diodes D 1 et D 2 respectivement dont l'autre borne est portée à la masse, d'autre part à des enroulements primaires 3 et 4 respectivement d'un transformateur dont les autres bornes sont portées à un potentiel V1 , l'enroulement secondaire dudit transformateur délivrant un signal ternaire Es dont le niveau est déterminé par une tension Vréf fournie aux deux émetteurs desdits transistors T1 et T2 . Application à la transmission de signaux à grande vitesse.The present invention relates to the amplification of signals transmitted in ternary code leaving a regeneration device. The device of the invention comprises a switch for the positive (resp. Negative) pulses consisting of two transistors T1 and T 2 having their bases connected at the input terminals and their emitters joined together, their collectors being connected to the emitters of two other transistors T3 and T4 respectively, the bases of said transistors T3 and T4 being grounded and the collectors joined on the one hand to diodes D 1 and D 2 respectively, the other terminal of which is grounded, on the other hand to primary windings 3 and 4 respectively of a transformer whose other terminals are brought to a potential V1, the secondary winding of said transformer delivering a ternary signal Es, the level of which is determined by a voltage Vref supplied to the two emitters of said transistors T1 and T2. Application to the transmission of high speed signals.
