| 摘 要： | 本文提出一种新的小波变换域选通滤波器，这种滤波器的选通域设计基于小波变换的局部模极大和局部模极小（以下称模极大和模极小），对于选择的代表重要信号特征的每个模极大，选通以其相邻的模极小为边界的一个区域内的小波变换．对比模拟实验结果显示新滤波器不仅计其简单而且滤波性能优良。

| Abstract: | In this paper, we present a new wavelet transform domain selecive filter which pass the wavelet transform only within some pase-regions in wavelet transform domain. Each of this pass-regions constracted based on a selected maximum,which represents a important signal feature, and two minima adjacent to the selected maximum. Experiments prove that the new filter not only implements easily but also gives good performance. |
