摘要
由RC元件与运算放大器组成的滤波器称为RC有源滤波器,其功能是让一定频率范围内的信号通过,抑制或急剧衰减此频率范围以外的信号。对有源RC双二阶滤波器展开研究并用MATLAB软件对不同参数的滤波网络进行了仿真,用单级正反馈电路实现了低通滤波器。
The filter consisting of RC elements and an operational amplifier is referred to as an RC active filter,its function is to make the signal of certain frequency range go through.In this paper,a double second-order active RC filter is studied,the filter network with different parameters is simulated with MATLAB software,and a single level positive feedback circuit is achieved to realize low pass filter.
