数字椭圆滤波器的Matlab设计与实现

Design and Realization of Digital Elliptic Filter Based on Matlab

介绍了数字椭圆型滤波器的基本理论和设计思想,给出了设计数字椭圆型滤波器的具体步骤,并通过一个带通滤波器为例来说明数字椭圆滤波器的Matlab具体实现过程,数字椭圆滤波器的设计非常简单、直观。最后对巴特沃斯、切比雪夫、椭圆函数3种滤波器的性能进行了比较。

The thesis introduces the elementary theory and the design thoughts of digital ellipse filter, and how to design it. It takes band pass filter for example to express the realization of the digital ellipse filter through on Matlab. We can conclude that it is easy and direct viewing to design the digital ellipse filter. In the end, it compares the function of Butterworth filter, Chebyshev filter and ellipse filter.
