Definitions

  • a demodulator section designed in such a manner makes it easy to add an additional demodulator.
  • the additional demodulator need only have a tri-state output terminal, as the others do, and be connected to the system bus.

Abstract

L'invention se rapporte à un récepteur à multiples protocoles qui comporte une section de démodulation. Cette section de démodulation comprend une pluralité de démodulateurs possédant chacun une borne de sortie à trois états destinée à la génération de données numériques démodulées. Les bornes de sortie à trois états sont couplées à un bus de signaux. Ce bus de signaux est, à son tour, couplé à un processeur de signaux, tel qu'un processeur de données de transport, destiné au traitement des données numériques démodulées.
