In a system where a second signal interferes with the detection of a first signal at an input, in which the second signal is composed of a low frequency component and a portion of the frequency spectrum that is higher than that of the first signal, then both signals are processed to eliminate such interferenceby filtering the second signal to eliminate the portion of the frequency spectrum that is higher than that of the first signal and eliminate the low frequency component of the second signal. Advantageously, such processing is done without affecting any low frequency component of the first signal.
Dans un système où un second signal brouille la détection d'un premier signal à une entrée et où ce second signal a une composante basse fréquence et une composante dont le spectre de fréquences est plus élevé que celui du premier signal, les deux signaux sont traités de façon à éliminer ce brouillage par filtrage du second signal pour supprimer la composante dont le spectre de fréquences est plus élevé que celui du premier signal et supprimer la composante basse fréquence du second signal. Ce traitement peut être effectué sans perturber les basses fréquences qui pourraient se trouver dans le premier signal.
