Abstract
a. L'invention concerne un montage pour la transmission de signaux de télévision, avec une entrée et une sortie de base de bande. b. En amont de l'entrée de base de bande est prévu un convertisseur de base de bande HF à étage mélangeur. Dans ce dernier, le signal de télévision est mélangé à une fréquence auxiliaire qui sert à décaler le signal de télévision dans la bande de base d'un écart de fréquence minimum, différent de zéro, de la porteuse vidéo. En aval de la sortie de la base de bande de la voie de transmission est prévu un convertisseur de base de bande HF opérant en sens inverse. c. Application à la transmission de signaux de télévision par des câbles coaxiaux, des lignes hertziennes et des voies de transmission à laser.at. The invention relates to an arrangement for the transmission of television signals, with a base band input and output. b. Upstream of the base band input is provided a base band converter HF mixer stage. In the latter, the television signal is mixed with an auxiliary frequency which serves to shift the television signal in the baseband by a minimum non-zero frequency deviation of the video carrier. Downstream from the output of the band base of the transmission path is provided an HF band base converter operating in the reverse direction. vs. Application to the transmission of television signals by coaxial cables, microwave lines and laser transmission paths.
