(FR) APPAREIL DE CODAGE VARIABLE POUR LA CONVERSION D'ENERGIE DE RESONANCE ET PROCEDE ASSOCIE
Abstract: front page image
(EN)A noise-shaping coder with variable or reconfigurable characteristics is disclosed. In one exemplary embodiment, an improved apparatus for signal modulation is disclosed. The apparatus (see figure 1) generally comprises a noise-shaping coder having programmable coefficients, (see figure 1, CSEL), programmable coder order (see figure 1, MSEL), programmable oversampling frequency (see figure 1, CKEN), and/or programmable dither (see figure 1, D). In a second exemplary embodiment, an improved method for implementing noise shaping coding is disclosed. The apparatus generally compromises a means for switching from one order coder to another order coder, as well as switching oversampling frequency.
(FR)L'invention concerne un codeur de mise en forme du bruit possédant des caractéristiques variables ou reconfigurables. Un mode de réalisation concerne un appareil amélioré de modulation de signaux. Cet appareil comprend généralement un codeur de mise en forme du bruit possédant des coefficients programmables, un ordre de codeur programmable, une fréquence de suréchantillonnage programmable et/ou un tremblement programmable. Un deuxième mode de réalisation concerne un procédé amélioré pour mettre en oeuvre un codage de mise en forme du bruit. L'appareil selon l'invention comprend généralement un moyen pour passer d'un ordre de codeur à un autre et pour modifier la fréquence de suréchantillonnage.
