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 new kind of filters Zero Spectral Moment Filters are intriduced, which properties are better than that of the common FIR filters, particularly for flatness on pass-band and stop-band. It includes the known wavelet filters, for examples of conjugate filters and biorthogonal filters.
