线性变换数字滤波器灵敏度分析的有效方法

A General Method for the Efficient Analysis of Sensitivities in Digital Filter Designed by Linear Transformations

线性变换方法的出现拓宽了由模拟原型设计低灵敏度数字滤波器的领域,形成众多的不同数字结构。本文提出一种灵敏度分析的新方法,它立足于对模拟原型滤波器的计算,故能适用于各种线性变换数字滤波器,简捷而有效,精确度高。

The linear transformation technique extended the field of designing low-sensitivity digital filters from analog prototype, and resulted in a number of different digital structures. In this paper, a new method is presented for fast and accurate calculation of sensitivities in above-mentioned digital filters Since the method is based on mainly dealing with the computation in the same analog prototype, it is suitable for all kind of those digital filters.
