基于双T网络的50Hz陷波电路设计
The Design of a 50Hz Frequency Trap Filter Based on Double T Net
摘要
以传统双T型无源带阻滤波器为基础并加入反馈电路设计了Q值可调的50Hz陷波电路。仿真实验表明该电路Q值连续可调且具有良好的选频特性,能最大程度地抑制50Hz工频干扰。
Abstract
Based on the traditional no source band-stop filter named double T and use feedback circuits ,a 50Hz frequency trap filter whose Q values are adjustable is designed .The simulation experiment indicates that the circuit can adjust the Q values continuously
