Abstract

Sélecteur toutes ondes de canaux de télévison avec synthétiseur de fréquences fonctionnant selon un schéma à double conversion de fréquences et gestion de sélection des canaux au moyen d'un synthétiseur. Le dispositif comprend un filtre d'entrée à bandes (1), un amplificateur de fréquence (2) incorporé dans un circuit de régulation automatique de gain, un premier dispositif de mixage (3), un premier filtre à bandes (4), un deuxième dispositif de mixage (5), un amplificateur de fréquence intermédiaire (6), deux oscillateurs: l'un de réaccordage (7) et un à longueur d'onde fixe (8), ainsi qu'une boucle de phase de commande automatique de fréquence, incluant un troisième dispositif de mixage (9), un troisième filtre à bandes (10), un premier (11), un deuxième (12) et un troisième (15) séparateurs, un discriminateur de fréquence-phase (13), un oscillateur de référence (14), un circuit intégro-différentiel (16), ainsi qu'un bloc de gestion (17). La sélection du canal de télévision s'effectue à partir du bloc de gestion par modification du coefficient de séparation de longeur d'onde dans le circuit de retour.
