Nous avons récemment développé un générateur de bruit composite programmable (P-CNG) qui peut facilement contrôler les paramètres de bruit tels que la puissance moyenne, la distribution de probabilité d'amplitude (APD) basée sur le temps, la distribution du taux de croisement, la distribution de fréquence d'occurrence et la durée des rafales. Deux applications du P-CNG sont démontrées pour montrer son utilité. Pour la première application, le bruit de classe A de Middleton est simulé. Une méthode de réglage des paramètres pour le bruit de classe A est démontrée. L'APD de la sortie P-CNG est en bon accord avec celui du vrai bruit de classe A. Dans la deuxième application, le P-CNG est utilisé pour un test d'évaluation subjective (test d'opinion) de la dégradation de l'image TV. Cinq modèles de bruit composite simples avec deux types d'APD sont utilisés. D'autres paramètres tels que la puissance moyenne restent constants. Les résultats expérimentaux montrent que l'enveloppe et l'APD des bruits composites n'influencent pas grandement l'évaluation subjective. Enfin les capacités du P-CNG sont montrées.

Abstract: We have recently developed a programmable composite noise generator (P-CNG) which can easily control noise parameters such as average power, time-based amplitude probability distribution (APD), crossing rate distribution, occurrence frequency distribution and burst duration. Two applications of the P-CNG are demonstrated to show its usefulness. For the first application, Middleton's Class A noise is simulated. A method of setting parameters for Class A noise is demonstrated. The APD of P-CNG output is in good agreement with that of true Class A noise. In the second application, the P-CNG is used for subjective evaluation test (opinion test) of TV picture degradation. Five simple composite noise models with two kinds of APD are used. Other parameters such as average power are kept constant. Experimental results show that the envelope and APD of composite noises do not greatly influence the subjective evaluation. Finally the capabilities of the P-CNG are shown.
