Abstract
L'invention se rapporte à un procédé et à un système apte à modifier la fréquence ou les spectres d'harmoniques d'une perturbation. Ce système comprend un générateur de sortie (26) et un générateur de réponse (24) qui coopèrent pour générer des signaux de régulation mis en forme en réponse à des premiers signaux d'entrée (23).
