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 orthogonal filter bank and the skew filter bank are discussed, and the relationship between them is discussed. The construction of wavelet is the fundamental problem in wavelet analysis, and the filter bank plays an important role in the construction of wavelet. The set of orthogonal wavelets, spline wavelets and biorthogonal wavelets are all constructed by using filter banks. These discussions are very useful in wavelet construction.
