Abstract: front page image
(EN)This ΔΣ modulator is provided with: a loop filter 30; a quantizer 36 that generates quantized data on the basis of the output of the loop filter 30; an internal pathway 42 that is connected to the loop filter 30 or the quantizer 36; and a compensator 38 that applies, to the internal pathway 42, a compensation signal for compensation of distortion occurring in the frequency component at target frequencies among frequency components of a pulse sequence corresponding to the quantized data.
(FR)La présente invention concerne un modulateur ΔΣ qui est pourvu d'un filtre de boucle (30), d'un quantificateur (36) qui génère des données quantifiées sur la base de la sortie du filtre de boucle (30), d'un chemin interne (42) qui est connecté au filtre de boucle (30) ou au quantificateur (36), et d'un compensateur (38) qui applique au chemin interne (42) un signal de compensation destiné à compenser la distorsion qui apparaît dans la composante de fréquence à des fréquences cibles d'une séquence d'impulsions correspondant aux données quantifiées.
(JA) ループフィルタ30と、ループフィルタ30の出力に基づいて、量子化データを生成する量子化器36と、ループフィルタ30又は量子化器36に接続された内部経路42と、量子化データに対応したパルス列の周波数成分のうちターゲット周波数の周波数成分に生じる歪の補償信号を、内部経路42に与える補償器38と、を備える。
