摘要
详细分析了信号在二分配器中正向传输与反向传输的过程,导出了二分配器反向传输时输出电平的计算公式,论述了二分配器在CATV上行系统中的应用。
This article particularly analyzes the process of forward and reverse direction transmission of signal in 2 -way divider, deduces the calculational expressions of output lever of the 2 -way divider in reverse Transmission and discusses the application of the 2 - way divider in upstream system of CATV.
