零谱矩滤波器系列
摘 要
鉴于一种新型的滤波器类别———零谱矩滤波器系列,其性能优于传统信号处理中的FIR滤波器,特别在通带的平滑度与阻带的衰减度方面尤佳。其特例包含了人们熟识的小波变换滤波器,如共轭滤波器与双正交滤波器。为此,对其进行简要介绍,以飨读者。

A Series of Zero Spectral Moment Filters
() Abstract
A new kind of filters——Zero SpectralMomentFilters are intriduced, which properties are better than that of the common FIR filters, particularly for flatness on passband and stopband. It includes the known wavelet filters, for examples of conjugate filters and biorthogonal filters.
