Abstract
(EN)
A noise separator for separating the probability density function of a predetermined noise component from the probability density function of a signal to be measured comprises a domain converting section for converting the probability density function into the spectrum of a frequency domain when the probability density function of the signal to be measured is given and a standard deviation calculating section for calculating the standard deviation of a random component of the noise contained in the signal to be measured according to the level of a predetermined frequency component in the main lobe of the spectrum
(FR)
L'invention porte sur un séparateur de bruit séparant la fonction de densité de probabilité d'un composant de bruit prédéterminé, de la fonction de densité de probabilité d'un signal à mesurer. Ledit séparateur comprend: une section de conversion de domaine convertissant la fonction de densité de probabilité en un spectre de domaine de fréquences lorsque la fonction de densité de probabilité du signal à mesurer est donnée; et une section de calcul de l'écart type d'un composé aléatoire du bruit contenu dans le signal à mesurer, en fonction du niveau d'un composant de fréquence prédéterminé du lobe principal du spectre.
