摘要
FIR数字滤波器是信息处理中的重要部件 .本文对该滤波器的线性相频特性进行分析 。
It's the important component in the process of deal with the information,that article are analysis the character of linear phase-frequency and we can know about how to get the structure directly.The another way is according to the character of central symmetry that can directly improving the structure.
