摘要
地面数字电视是电视技术的前沿技术.在对地面数字电视发射机进行维护时,激励器的运行状态往往容易被忽视,而激励器一旦发生故障,通常会导致发射系统的不稳定.对此,深入剖析地面数字电视发射系统的基本原理,聚焦激励器等关键设备的技术细节,对于提升地面数字电视发射系统的运维管理水平具有重要意义.
Abstract
Terrestrial digital television is the advanced technology of television technology.In the maintenance of terrestrial digital television transmitter,the operating state of the exciter is easy to be ignored,and once the exciter fails,it usually leads to the instability of the transmitting system.In this regard,in-depth analysis of the basic principle of terrestrial digital TV launch system,focusing on the technical details of key equipment such as the driver,is of great significance for improving the level of operation and maintenance management of terrestrial digital TV launch system.
