本文从信号分配和前端设备配置两方面,介绍了小型电缆电视多路传输系统的设计方法。该方法以一个实例为线索,其信号分配灵活多样,既反映了系统设计的一般方法,又体现了小型系统简便易行的设计特点,因而,对设想安装小型电缆电视系统的单位具有参考价值。同时,该方法也可作为小型共用天线电视系统的设计参考。
This article introduces the design method of small cable television multiplex transmission system from two aspects of signal distribution and front-end equipment configuration. Taking one example as a clue, the method is flexible and diverse in signal distribution. It not only reflects the general method of system design, but also reflects the design features of small-scale system. Therefore, it is of reference value to the unit that is supposed to install a small cable TV system. At the same time, the method can also be used as a reference design for small common antenna TV system.
