Title (EN) IMPROVED BINARY DETECTING AND THRESHOLD CIRCUIT
(FR) CIRCUIT DE SEUIL ET DE DETECTION BINAIRE
Abstract: front page image
(EN)A repeating binary word detecting circuit (14-44) produces a plurality of phase shifted samples of the logic of each binary bit forming the word. The plurality of samples are respectively compared (17) with a stored sequence of bits (18) forming the binary word to be detected. These comparisons are made for every possible beginning sequence of samples or stored bits between the time of two samples. An indication is given if a selected number of comparisons agree. A threshold circuit (41) produces a decode output in response to a selected number of indications based on at least two phase shifted samples.
(FR)Un circuit de detection de mots binaires de repetition (14-44) produit une pluralite d'echantillons dephases de la logique de chaque bit binaire formant le mot. La pluralite d'echantillons sont compares respectivement (17) a une sequence stockee de bits (18) formant le mot binaire a detecter. Ces comparaisons sont effectuees pour chaque sequence de depart possible d'echantillons ou de bits stockes entre l'intervalle de temps de deux echantillons. Une indication est donnee si un nombre selectionne de comparaison correspond. Un circuit de seuil (41) produit une sortie de decodage en reponse a un nombre selectionne d'indications base sur au moins deux echantillons dephases.
