Title (EN) ADAPTIVE MULTI-BIT DELTA AND SIGMA-DELTA MODULATION
(FR) MODULATION DELTA ET SIGMA-DELTA MULTIBITS ADAPTATIVE
Abstract: front page image
(EN)An adaptive multi-bit delta and sigma-delta modulation (10) and demodulation technique, wherein a one-bit modulator generates a binary output signal from an analog input signal and a multi-bit adapter (24) for generating a scaling signal for scaling a step-size of the sigma-delta modulator.
(FR)L'invention concerne une technique de modulation et démodulation multibits delta et sigma-delta adaptative dans laquelle un modulateur à un seul bit génère un signal de sortie binaire à partir d'un signal d'entrée analogique, et un adaptateur multibits génère un signal de mise à l'échelle permettant de définir l'amplitude du pas du modulateur sigma-delta.
