有源滤波器的CAD——介绍一个通用优化设计程序

CAD of Active Filters Introduce a Universal Optimized Program

本文介绍用最优化方法设计有源滤波器各元件参数的通用程序。这个程序可用于各种电路结构和频率特性的滤波器设计。由程序自动形成节点导纳矩阵和求取逼近函数作为设计的预期响应。程序具有通用性、使用方便和设计精度高等特点,并能在微机上运行。

This paper introduces a universal program to design parameters of the elements of active filters by using optimization method. The program can be used in filter designs of various circuit structures and frequency responds. The node admittance matrix and approximate function (as an expected response) are formed automatically by the program. The advantages of the program are universality, convenience and higher design accuracy. It can be operated on micro-computers.
