摘　　要：从信号处理和工程应用的角度出发,避开了复杂的数学公式推导,阐述了双通道滤波器组与小波变换的关系,并讨论了母小波函数的选择可归结为正交镜像滤波器的设计。In this paper, it is expounded the relationship of two-channel perfect reconstruction filter banks to wavelet transform on the base of signal processing and engineering application; Avoiding complex math formula deduction, the selection of a desirable mother wavelet function becomes the design of two-channel perfect reconstruction filter banks.
