Abstract

a. Circuit de traitement d'un signal de télévision. b. Circuit caractérisé en ce qu'il comporte un circuit bouchon branché dans le chemin du signal de l'amplificateur IF pour rejeter tout signal gênant fourni par un oscillateur local d'un autre dispositif d'accord relié à la même borne d'antenne commune et ayant une fréquence voisine de celle d'un signal IF pour éviter la formation d'un signal de battement par interférence réciproque entre le signal IF et le signal gênant.
