Abstract

Le procédé de mesure des valeurs crête et puissance d'un signal audiofréquence S, comprend des étapes : de numérisation du signal original, de calibration du signal numérisé, de détermination d'instants d'actualisation des mesures du signal sur la base d'un critère associé à la valeur du signal lui-même, de mise en place d'une séquence rapide de mesure de la crête du signal numérisé et calibré, de mise en place d'une séquence rapide de mesure de la puissance du signal numérisé et calibré, d'acquisition des mesures de crête et de puissance représentatives du signal numérisé et calibré selon les instants d'actualisation du signal, d'optimisation de la rapidité de la mesure suivant la nature du signal numérisé et calibré. d'optimisation de la pertinence de la mesure sur un signal numérisé et calibré large bande et de grande dynamique.
