广播电视微波传输电路的数字化改造

Digital Transformation of Microwave Transmission Circuit in Broadcasting and Television

广播电视的信号传输包括卫星传输、微波传输以及光缆传输3种不同的形式。与其他2种传输方式相比,微波传输具有组网结构简单、耗费成本低以及抗干扰能力强的优势。因此,微波传输对广播电视的信号传输体系非常重要。与模拟微波电路传输相比,数字微波电路传输可以传输更大容量的信号,而且接收的信号质量更好。基于该背景,分析和探讨广东省广播电视微波传输电路的数字化改造问题。

The signal transmission of broadcasting and television includes three different forms:satellite,microwave,and optical cable.Compared with the other two transmission methods,microwave transmission has the advantages of simple network structure,low cost consumption,and strong anti-interference ability.Therefore,microwave transmission is very important for the signal transmission system of broadcasting and television.Compared with analog microwave circuit transmission,digital microwave circuit transmission can transmit larger capacity signals and receive better signal quality.Based on this background,the digital transformation of microwave transmission circuits for broadcasting and television in Guangdong Province was analyzed and discussed.
