摘要
论述同轴电缆频率特性的差异，对均衡器补偿特性的适配要求，及对链路电平平坦特性的影响，通过数学分析导出了有关函数表达式和计算公式，论证了有关结论。最后提出了按电缆衰减函数的倾斜系数进行分档设计、生产均衡器，使之与电缆适配的设想。
This paper discusses the discrepancy in coaxial cable frequency characteristics and requirements to the suitablity of the compensation characteristics of equalizer,derives expressions of related functions and calculation fromulae by mathematical analysis,and comes to some conclusions concerned.Finally an idea is proposed to design and manufacture equalizers in different quality grades according to the slope factor in the attenuation characteristics of coaxial cable so that the equalizers fit the cables.
