Abstract

L'invention concerne les dispositifs d'atterrissage aux instruments. L'appareil de l'invention est destiné à déterminer la fréquence d'un signal appliqué sur une borne d'entrée 100. Dans ce but, il élabore des signaux scalaires qui représentent la fréquence et l'amplitude du signal reçu et il calcule la valeur moyenne des signaux scalaires sur un certain nombre d'intervalles de temps, avant de diviser ces signaux pour obtenir un signal de sortie représentant la fréquence moyenne du signal reçu. Application aux dispositifs de radionavigation Doppler.
