摘　　要：本文通过理论分析和计算，提出一种可同时调整中心频率和品质因数的非对称有源陷波器设计，并通过生物放大器中针对消除市网电源信号干扰的模拟实验数据证实。ased on strict analysis and calculation, an asymmetric activetrop filter of adjustable freguency and Qfactor was designed. And by means of analog ous experimental data in biological amplifier to eliminate 50Hz power interference, it was proved that the trop filter showed more advantages and practicability than the doubleT symmetric activetrop filter.
