speech filter

2-D adapting filter make original character of speech signal be kept.

而采用二维自适应滤波后，语音的包络形状得到较好地保持，使原始语音信号的特征完整。

The principle and design process of the Quadrature Mirror Filter ( QMF) in 16 kbit/ s SB& PC speech compression coding system are discussed. The hardware and software structures for implementing QMF to split band are also given in the paper.

本文讨论了16kbit/s分带自适应（SB&APC）预测语音压缩编码系统中的正交镜象滤波器（QMF）的原理和设计过程，并给出了实现QMF的硬件和软件结构。
