Abstract

Montage de recherche dans lequel des valeurs de tension déterminées sont affectées aux fréquences de la porteuse transposée dans la bande passante FI et déterminées par un circuit intégré de contrôle 8. Les valeurs de tension sont transmises par un fil 9 unique à un circuit intégré de commande 11, qui les traduit pour l'action désirée sur la recherche (CAF comprise).Research arrangement in which determined voltage values are assigned to the frequencies of the carrier transposed into the pass band IF and determined by a control integrated circuit 8. The voltage values are transmitted by a single wire 9 to a control integrated circuit 11, which translates them for the desired action on research (including CAF).
