摘要
讨论了正交滤波器组和斜交滤波器组 ,以及它们之间的关系 .小波的构造是小波分析中的根本问题 .而在小波的构造中 ,滤波器组起着重要的作用 .紧支集正交小波、样条小波和双正交小波等都是利用滤波器组来构造的 .这些讨论在小波构造中是非常有用的 .
The construction of wavelet is a fundamental problem. The wavelet filters play an important role in constructing wavelet. Compactly supported orthonormal wavelet, compactly supported biorthogonal wavelet, and B spline wavelet, etc. are constructed by means of the filters. In this paper, the orthonormal and non orthogonal wavelets, as well as relation between them, are discussed. These investigations are extremely useful in constructing wavelet.
