摘要
在数字时代,广播电视发挥着非常重要的作用,为人们的生活增添乐趣,满足人们的精神生活需求,也是人们获取外界事件信息和休闲娱乐的必要途径。无线传输技术的广泛应用,扩大了我国数字电视的覆盖面,提高了广播电视节目质量。当前,随着我国经济社会的快速发展,人民物质生活水平显着提高,数字电视已成为必备的家用电器。数字电视前端系统对整个电视网络的正常运行和电视信号的质量都有很大的影响。目前,中国居民收看的电视节目信号来源主要是卫星传输信号,以及地面直传和有线数字电视传输信号。随着我国全面进入数字信息时代,数字信息传输技术已经渗透到社会的方方面面,人们对数字信息传输提出了更高的要求,这促使我国未来的信号传输基础设施要致力于提高信号传输质量,数字信息传输。文中研究分析了地面数字电视微波信号源的设计与实现,以供参考。
In the digital age,radio and television play a very important role in adding fun to people's life and meeting people's spiritual life needs.It is also a necessary way for people to obtain external event information and leisure and entertainment.The wide application of wireless transmission technology has expanded the coverage of digital TV in China and improved the quality of radio and television programs.At present,with the rapid development of China's economy and society and the significant improvement of people's material living standards,digital TV has become an essential household appliance.Digital TV front-end system has a great impact on the normal operation of the whole TV network and the quality of TV signal.At present,the signal sources of TV programs watched by Chinese residents are mainly satellite transmission signals,as well as ground direct transmission and cable digital TV transmission signals.As China has fully entered the digital information age,digital information transmission technology has penetrated into all aspects of society.People put forward higher requirements for digital information transmission,which urges China's future signal transmission infrastructure to improve the quality of signal transmission and digital information transmission.This paper studies and analyzes the design and implementation of terrestrial digital TV microwave signal source for reference.
