摘要
本文对椭圆函数滤波器边带特性优化方法进行了研究,给出了一种新方法的详细分析、算法和设计实例。该方法充分利用滤波器阶数余量,通过相应的计算方法在不增加阶数的前提下使滤波器边带选择特性最大化,有效地减小了过渡带宽。
In this paper, some thoroughly research about the technique for optimizing the band-edge characteristic of elliptic function filter are presented, and detail theory analysis, algorithm and design example of a novel method are described. This proposed technique, which minimizes the residue value of filter order, allows designer to maximize the band-edge selectivity （BES） of elliptic filters without increasing filter order by given additional calculation steps, so that effectively narrows the transition band,
