Title (EN) METHOD AND APPARATUS FOR SIGNAL PROCESSING
(FR) PROCÉDÉ ET APPAREIL POUR UN TRAITEMENT DE SIGNAL
(ZH) 一种对信号进行处理的方法及装置
Abstract:
(EN) A method and an apparatus for signal processing: implementing step-by-step orthogonal decomposition of an original signal to be inputted; on the basis of the number of layers of orthogonal decomposition and the edge high frequency bandwidth of the original signal after orthogonal decomposition, generating a finite-length unit impulse response FIR filter; using the FIR filter to filter the edge high-frequency signal of the original signal; and, after passing the signal obtained after filtering and the low frequency signal obtained at each stage of orthogonal decomposition through an orthogonal filter bank, implementing signal synthesis processing.
(FR) La présente invention concerne un procédé et un appareil de traitement de signal consistant à mettre en œuvre une décomposition orthogonale pas à pas d'un signal d'origine à entrer ; sur la base du nombre de couches de décomposition orthogonale et de la bande passante de haute fréquence de bord du signal d'origine après la décomposition orthogonale, générer un filtre FIR à réponse impulsionnelle unitaire de longueur finie ; utiliser le filtre FIR pour filtrer le signal haute fréquence de bord du signal d'origine ; et, après le passage du signal obtenu après filtrage et le signal basse fréquence obtenu à chaque étape de la décomposition orthogonale par l'intermédiaire d'une banque de filtres orthogonaux, mettre en œuvre un traitement de synthèse de signal.
(ZH) 一种对信号进行处理的方法及装置,将需要输入的原始信号进行逐级正交分解,根据正交分解的层数和正交分解后原始信号的边缘高频带宽,生成有限长度单位冲击响应FIR滤波器,采用FIR滤波器对原始信号的边缘高频信号进行滤波,将滤波后得到的信号以及进行逐级正交分解后每一级得到的低频信号通过正交滤波器组后进行信号合成处理。
