摘　　要：根据电磁兼容理论,提出了一种解决无线电广播电台发射塔附近的住户的固定电话总会存在广播音串扰的问题的方法。从分析电磁骚扰源、耦合途径和敏感设备入手,通过对有源器件的选型和印制板设计、接地设计、屏蔽设计、滤波设计和瞬态骚扰抑制对电话机进行电磁兼容设计。最后给出了仿真数据,取得了较好的效果。It provides a solution to solve problem of fixed- line telephone connecting to radio disturbing phone conversation where residence living around radio tower based on electromagnetic compatibility theory. It gets a better result from simulation date by designing for different models of telephone electromagnetic compatibility about Active device,PCB,Grounding Connection,Shielding,Filter,Transient Disturbance Suppression and Etc after analyzing electromagnetic disturbance source,coupled channels,and sensitive equipment.
