Title (EN) ADAPTIVE SIGMA-DELTA MODULATION WITH IMPROVED DYNAMIC RANGE
(FR) MODULATION SIGMA-DELTA ADAPTATIVE AVEC UNE GAMME DYNAMIQUE AMELIOREE
Abstract: front page image
(EN)An adaptive sigma-delta modulation and demodulation technique, wherein a quantizer step-size is adapted based on estimates of an input signal to the quantizer, rather than on estimates of an input signal to the modulator.
(FR)L'invention concerne une technique de modulation et démodulation sigma-delta adaptative, dans laquelle un pas de progression de quantificateur est adapté selon les estimations d'un signal d'entrée dans le quantificateur, plutôt que sur des estimations d'un signal d'entrée dans le modulateur.
