资料介绍

深入研究多重反馈二阶有源低通滤波器典型电路,提出一种参数优化设计的新方法。设计多重反馈二阶巴特沃斯有源低通滤波器,并用Multisim 13电路仿真软件对其进行仿真分析。仿真结果表明,采用该优化设计方法设计的有源滤波器幅频特性良好、系统稳定可靠、易实现。另外,不同元器件的精度对滤波器特性的影响是不同的,实际应用中可合理选择各元器件精度,在保证质量的前提下降低成本。

A new method of parameter optimization design is proposed by means of the in-depth study of the typical circuit of second-order active low-pass filter with multiple feedbacks. The second-order Butterworth active low-pass filter with multiple feedbacks was designed. The simulation analysis is performed for the filter by using the Multisim 13 circuit simulation simulation results show that the active filter designed by the optimization design method has a good amplitude-frequency characteristic,and the system is stable,reliable and easy to implement. The precision of different components has different effects on filter features,so in practical application,it is advisable to rationally select the precision of various components,so as to reduce th...
