多功能R有源滤波器电路

Multi function R active Filter

】本文给出了能同时实现低通（ＬＰ）、高通（ＨＰ）、带通（ＢＰ）的Ｒ有源滤波器电路及电路的设计方程，对其中的一个电路进行了机辅分析和设计，实验结果验证了理论的正确性。

Some multi function R active filter circuits and their design formulas are given in this paper.With them,the low pass,high pass and band pass functions may be realized simultaneously.One of these circuits as an example is analysed with computing aid. The correctness of the theory has been verified by the conclusion of experiment.
