摘要
本文详细定性.定量分析了电缆电视网的载噪比、载波互调比、交扰调制比和最大级联数,系统的工作余量、最佳放大增益、提出了对干线放大器的要求及实际应用.
In the article, we analysed in qualily and quantity the carricr-to-noisc ratio, carrier wave coordinate ratio, alternate interference modulate ratio and the maximum number of scries in the CATV-nctwork.We also talked about the demands of the system in the work margin the optimum gain and the main amplifier, and the practical use of the CATV netword
