广义Hilbert变换将传统的Hilbert变换由整数阶向分数阶的推广,其应用领域也得到了扩展。文章主要研究设计广义Hilbert滤波器时,窗函数的选择问题以及对滤波器的误差进行分析,并给出了分析结果。
A generalization of Hilbert transform is traditional Hilbert transform from integral order to fractional order and the application fields are extended. The choice of window function in generation of Hilbert filter designed is discussed in this paper. The error of filter is analyzed and results are obtained.
