Abstract

Abstract Translated from French Transmission à la fréquence porteuse d'impulsions contenant les informations dans position de leurs flancs, avec un rapport signal/bruit et tension parasite élevé. Deux oscillateurs de porteuse 5, 6 sont utilisés à l'émission, chacun d'eux étant branché avec une phase constante par les flancs de branchement des impulsions et le second, avec une phase constante, par les flancs de coupure Le démodulateur 13 à 16 de réception traduit la position relative des débuts des trains d'ondes délivrés alternativement par les deux oscillateurs. Les instants de branchement et de coupure d'un oscillateur sont décalés par rapport aux temps de coupure et de branchement du second oscillateur. Transmission at the carrier frequency of pulses containing the information in the position of their flanks, with a signal / noise ratio and high parasitic voltage. Two carrier oscillators 5, 6 are used on transmission, each of them being connected with a constant phase by the connection edges of the pulses and the second, with a constant phase, by the cutoff edges The demodulator 13 to 16 reception reflects the relative position of the beginnings of the wave trains delivered alternately by the two oscillators. The switching on and off times of an oscillator are offset with respect to the switching off and switching times of the second oscillator.
