摘　　要：该文讨论了多元小波滤波器的矩阵扩充问题.文献[7]给出了当伸缩矩阵为2I_(2×2)时的矩阵扩充方法,该文得出了当伸缩矩阵A满足det A=4时的方法.This note focuses on wavelets and filter banks. In [7] the problem of matrix extension a matrix extension method was in the theory of multivariate given for low-pass filter with linear phase in the bivariate case with special dilation matrix 2I2×2. The authors extend this result to general case with the determinant of the dilation matrix being 4.

关 键 词：多元小波 滤波器 矩阵扩充.
