目前,各省(市)电视台的信号普遍采用微波接力的方法,传输到所属市(地)电视台。据不完全统计,用来传送电视信号的专用微波网,全国总长度约有十几万公里。为充分发挥这些设备的效益,本文就如何利用一个微波波道,既传电视信号又传电话信号的有关问题,作一些粗浅的分析,并将其初步实验效果作一下扼要介绍,供从事微波技术的同志参考。
At present, the signals of television stations of various provinces (cities) generally use the method of microwave relay to be transmitted to the television stations of their respective cities (prefectures). According to incomplete statistics, a special microwave network for transmitting television signals has a total length of about 100,000 kilometers. In order to give full play to the benefits of these devices, this article on how to use a microwave channel, both the transmission of television signals and transmission of telephone signals related to some superficial analysis and preliminary experimental results make a brief introduction for microwave technology Comrade reference.
