资料介绍

结合目前低频电子设备普遍存在受50Hz工频干扰的现状,通过对滤波电路的深入研究,借助电路仿真工具,研究并设计一种能够有效滤除50Hz工频及其二次谐波的可调Q值双T有源带阻滤波电路.该电路具有良好的滤波、放大、反馈、调节功能,在低频信号信息处理、数据传输、抑制干扰等方面都可以得到广泛应用.

Considering the situation of the low--frequency electronic equipment which is generally affected by the 50Hz power frequency interference, based on the thorough study of filter circuits, a tunable Q value double T active filter circuits which can effectively filter out 50 Hz frequency and its second harmonic is made and designed with the help of circuit simulated tools. The circuit has excellent filtering, amplification, feedback, and regulation function, which can be widely applied in the fields of low frequency signal and information process, data transmission, and interference suppression.
