摘要
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。
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.
