摘要
针对小波变换的关键环节——小波分解和重构,提出基于离散小波变换(DWT)的双通道滤波器设计方案,并进一步阐明双通道双正交性滤波器设计应注意的几个问题。
The wavelets transform theory is expounded in detail. The scheme of two channels filter based on discretetime wavelet transform (DWT) is designed for the key problem of wavelets transform that is wavelets decompose and compose, and further a few key points on designing two channels double orthogonal filter are discussed.
