摘要
抽取滤波器在过采样∑ΔＡ／Ｄ变换系统中起着最终滤除带外噪声以及恢复奈奎斯特抽样频率的作用。位串行算法由于能节约硬件资源和减小传输延迟等优点而在ＶＬＳＩ实现中广泛的应用，本文讨论用位串行算法实现抽取滤波器的结构。
:In oversampling ∑ΔA/D converter,the decimator finally gets rid of the noises out of the base band and then samples the oversamplingrate data to get the Nyquistfrequency data stream.BitSerial algorithm is highly attractively in VLSI implementation when taking the hardware resourse,propagation delay.,etc,into consideration.An architecture of implementing decimators employing bitserial algorithm is described in this paper.
