A discriminating apparatus for digital audio broadcasting according to the present invention includes a delay means for delaying an input signal by a time corresponding to a period of an effective symbol in a symbol, a correlation means for judging whether any correlation exists or not between the input signal and a delayed signal from the delay means, a moving average means for calculating a moving average of an output of the correlation means in a period corresponding to a guard interval in the symbol, and a comparing means for comparing an output of the moving average means with a threshold level. It is determined based on an output of the comparing means whether or not the input signal is a digital audio broadcasting signal.

Appareil de discrimination pour la radiodiffusion numérique comprenant : un élément de retard pour retarder un signal d'entrée d'une durée correspondant à la durée d'un symbole effectif dans un symbole, un élément d'établissement de corrélations pour déterminer si une corrélation existe ou non entre le signal d'entrée et un signal retardé provenant de l'élément de retard, un élément de calcul de moyennes mobiles pour calculer la moyenne mobile d'une sortie de l'élément d'établissement de corrélations pour une durée correspondant à un intervalle de garde dans le symbole, et un élément de comparaison pour comparer une sortie de l'élément de calcul de moyennes mobiles à un seuil. On détermine, selon une sortie de l'élément de comparaison, si le signal d'entrée est un signal de radiodiffusion numérique ou non.
