摘要
广播电视的传播流程比较复杂,传播过程涉及信号管理、强弱电驱动、传输、采集等,这些是确保广播电视信号高质量、高效率传播的关键要素,只有提高和保证这些要素的抗干扰能力,强化抗干扰技术,广播电视网络才能正常运行。为了使广播电视持续运行,国家对其投入大量资金,尽管如此信号在传播过程中大量的问题仍旧存在。基于此,就干扰类型进行分析,对干扰因素进行剖析,并进一步对抗干扰技术进行研究。
Radio and television transmission process is quite complex,involving in the propagation of the signal management,strong or weak electric drive,transmission,acquisition,etc.These are the key elements to ensure high quality and high efficiency of radio and television signal transmission.Only by improving the antiinterference ability of these elements,strengthen the anti-interference technology,can we ensure normal operation of radio and television network.In order to keep the radio and television running,our country has invested a lot of money,but in spite of this,there are still a lot of problems in the transmission of the signal.Based on this,this paper analyzes the interference types,and the interference factors,and further studies the anti-interference technology.
