Abstract

Un appareil de mesure d'intensité de champ est réglé à un seuil donné. Des mesures sont effectuées à des moments quasi périodiques. Un appareil de compage, avec un accumulateur, ajoute n valeurs de comptage à l'accumulateur quand l'intensité de champ dépasse le seuil et y soustrait k valeurs quand l'intensité est en-dessous du seuil. L'accumulateur présente une valeur de départ donnée et un état de comptage maximal ou minimal et il détermine un critère de couplage pour un état de comptage donné. L'intensité de champ se situe dans des sections du faisceau herzien, dont pour appareils de radio.
