Abstract

Poste pour liaison duplex, présentant une consommation d'énergie réduite pendant l'état de veille. Pendant l'état de veille, le circuit 12 ne fournit la haute-tension nécessaire au fonctionnement du poste qu'à intervalles réguliers, sa tension d'alimentation lui étant fournie à travers un circuit interrupteur 10 commandé par un circuit oscillateur 11. Lorsque, pendant l'état de veille, le poste reçoit un signal dont la fréquence est comprise dans sa bande de fréquences de réception, le signal qui en résulte à la sortie du circuit discriminateur, 4, bloque le circuit oscillateur, 11; le circuit 12 est alors alimenté en permanence à travers le circuit interrupteur 10 et fournit une haute-tension permanente. Application, en particulier, aux postes émetteurs-récepteurs portables et portatifs.
