A modulated signal, having a varying magnitude signal envelope, is conditioned, such as to facilitate amplification (500). Minimum values are determined values for portions of the signal envelope (520, 530), and a window expansion function applied to scale each portion of the signal envelope having a minimum value below a particular threshold, such that each scaled portion has a new minimum value of at least the particular threshold (535, 540, 550, 555).
Un signal modulé, présentant une enveloppe de signal d'une amplitude variable, est conditionné de manière à faciliter l'amplification (500). Des valeurs minimales sont définies comme valeurs de parties d'enveloppe de signal (520, 530) et une fonction d'expansion de fenêtre est appliquée de manière à échelonner chaque partie d'enveloppe de signal présentant une valeur minimale se situant en deçà d'un seuil donné, de telle sorte que chaque partie échelonnée présente une nouvelle valeur minimale correspondant au minimum à ce seuil (535, 540, 550, 555).
