摘要
本文介绍了有源滤波器设计的一种新方法——归一化计算机辅助设计方法.提供了低通、高通有源滤波器的设计与分析程序.采用该程序可设计1～10阶低通、高通有源滤波器.本程序采用人机对话方式输入设计有源滤波器的基本参数,即可根据设计要求确定滤波器所需的阶数和节数.计算电路中各元件的数值并绘制出滤波器的幅频、相频特性曲线.
The unified design method for the active filtersis introduced, and a program with which the low-pass and high-pass active lilt- ers under 10th order can be designed is suggested.Using the form of dialogue between person and computer,when the basic parpmeters for the active filter,i.e.the steps and sections needed according to the design and sections needed according to the design demand is im- put the numerical value of eachcircuit component and the curve of fre- quency response for the designed active filter Will be simutaneously displayed.
