摘要
本文提出具有输出网络的双运放二阶有源R滤波器的综合设计原理.用无源网络的综合方法解决有源网络的综合问题.在实现双二次函数的滤波特性时文中提出的电路具有输出阻抗低的优点.
A synthetic prineiple of active R filters with two operational amplifiers and output network is proposecl in this paper. The problem of synthesizing active network is solved with the help of the method in passive network syntheses. The circuit in this paper has a character of lower output impedance in the realization of the filter discrimination of dual second function.
