摘要
设计了一种典型的Butterworth滤波器,分析了借助MATLAB的两种常用设计方法的优劣.利用分析结果,优化了设计方法,得到了较好结果,消除了双线性变换设计法的弊端,大大改进了滤波器的性能.
A tipical Butterworth filter is designed. The advantages and disadvantages between two commonly used designing approaches are analyzed based on MATLAB. By making use of the research consequences, the drawback of bilinear transformation is removed, and the performance of the filter is improved greatly.
