摘要
为了解决发射塔资源短缺问题,可采用调频和电视多频道共塔技术。调频和电视多频道共塔技术中的关键设备是多频道合成器。多频道合成器设计是否合理,直接影响到整个系统的性能。探讨多频道合成器基本部件以及几种典型的结构对技术指标的影响以及改进方法。
In order to resolve source shortage of television tower, adopting frequency modulation and television multi- channel with total tower. The most important equipment is multi- channel synthesizer, it impacts capacity of whole system. The specifications, basic components and a few typical structures of multiple- channel synthesizer are persented in this paper.
