摘　　要：完全重构滤波器组的设计在信号处理领域极为实用,尤其与小波分析相结合,成为计算离散小波变换的有效方法。本文就滤波器组与小波的设计进行了阐述和比较,并采用图形化工具LabVIEW直观地进行了一些实例分析,取得较好的效果。Perfect reconstruction(PR) filter banks were recognized as useful in signal processing, particularly after the combination with wavelet analysis. Since then, it has become an efficient technique for computing discrete wavelet transform. The paper expounds and compares the design of wavelet and perfect reconstruction filter banks in detail. Moreover, we get some intuitional analysis of examples by the graphical tool-Lab VIEW.
