Title (EN) SIGNAL LEVEL DETECTION APPARATUS AND DETECTION METHOD, AND SIGNAL LEVEL DISPLAY APPARATUS
(FR) APPAREIL DE DETECTION DU NIVEAU DE SIGNAL ET PROCEDE DE DETECTION, ET APPAREIL D'AFFICHAGE DU NIVEAU DE SIGNAL
Abstract:
(EN) A signal level detection apparatus for detecting the level of a 1−bit digital signal. The apparatus includes an audio decoder (5), a level detection bock (12), and a display block (13). 1−bit digital signals decoded by the audio decoder (5) are successively and continuously input and the 0 or 1 occupation ratio in the 1−bit digital signal string consisting of a predetermined n signals is counted to detect the level of the 1−bit digital signal by the level detection block (12). The signal level detected by the level detection block is displayed on the display block (13).
(FR) L'invention se rapporte à un appareil de détection du niveau de signal servant à détecter le niveau d'un signal numérique de 1 bit. Cet appareil comprend un décodeur audio (5), un bloc de détection de niveau (12), et un bloc d'affichage (13). Les signaux numériques à un bit décodés par le décodeur audio (5) sont successivement et en continu entrés et l'indice d'occupation 0 ou 1 dans la chaîne de signaux numériques à 1 bit consistant en un signal n prédéterminé est calculé afin de détecter le niveau de signaux numériques à 1 bit au moyen du bloc de détection de niveau (12). Le niveau de signal détecté par le bloc de détection de niveau est affiché sur le bloc d'affichage (13).
