摘要

介绍了一种面向CAD的无源椭圆滤波器合成方法。各种技术的结合导致一个简单的用户友好的算法，可以帮助设计非常高阶的这种滤波器。本文还介绍了一个典型的9/sup /度滤波器的计算机模拟，该滤波器的f/sub / c/ f比为1.1，衰减为70 dB。利用这些原型值设计了一个带阻滤波器，并将其安装在东部铁路的通信信道中。

A CAD methodology for ultra-sharp roll-off elliptic band-stop filter for suppression of adjacent channel interference

A CAD oriented approach for synthesis of passive elliptic filters is outlined. A combination of various techniques leads to a simple user friendly algorithm which can help in designing very high orders of such filters. Also presented is the computer simulation of a typical 9/sup th/ degree filter which gives a 70 dB attenuation of f/sub c//f ratio of 1.1. A bandstop filter is designed with these prototype values and installed in the communication channels of Eastern Railways.
