三极点低通有源滤波器的设计

Design of a 3-Pole-LP Active Filter

以巴特沃斯等滤波器为例,介绍一种通过求解迭代方程根的计算机程序来实现,由单一放大器构成的任意增益的三极点低通有源滤波器的设计方法。

Taking Butterworth filters as an example,the computing program to find roots of iterative equations is completed,herewith a design method introduced by means of a single amplifier having constituted a 3poleLP active filter of any value available to be gained.
