摘　　要：用电学理论分析了高速数字同步系统电磁兼容的实施处理方法及晃动补偿法原理 对电场 f干扰的屏蔽 ,采用电导率高的金属Cu或Al材料 ,其屏蔽反射损耗R理想 ;对磁场的屏蔽 ,采用高导磁率的坡莫合金材料 ,其屏蔽反射损耗R理想 ;采用EMI滤波器 ,电容温度系数小、精度高 ,电感材料呈现的等效电阻R与吸收的干扰频段吻合 ,达到最大抑制电磁干扰的效率The implementary processing means of electromagnetic compatible and the jitter compensation principle in the high-speed digital synchronization system based on the electrics theory are analyzed.For the shielding of the electric field f interference,used the metal Cu or the material Al which has high conductance and ideal shielding echo wastage R.For the shielding of the magnetic field,used the permalloy material which has high permeability and appropriate shielding echo wastage R,used the EMI filter which has small capacitance temperature coefficient and high precision,the equivalent resistance R which inductance material presents tallies with sorbed band interference.The system can achieve maximal efficiency of restrain electromagnetic interference,the experimenta prove that these means are in effect.
