摘要
本文论证了电信线对电磁干扰衰减,阐述了衰减与敏感系数的关系,并推导了衰减的计算公式,然后说明了CCITT现有计算公式未计入衰减.
The attenuation of electromagnetic interference in telecommunication lines is discussed. Describing the relation between the attenuation and the sensitive coefficient, deducting a set of calculating formulas, the author suggests that it is necessary to multiply an attenuation factor when using the formulas recommended by CCITT to calculate the influences of Electromagnetic interference.
