对广播发射有关键影响的一个重要装置就是广播发射机,对广播发射来说,目前中波数字调幅广播技术属于广播发射的核心技术,也是影响广播发射的重要因素。不过在使用中波数字调幅技术的过程中经常会存在一些故障,这对广播发射会带来一定的困扰。为了确保广播发射机的正常进行,对于经常出现的一些故障就要掌握其出现的原因,还要制定出相应的对策。文中笔者首先介绍了中波数字调幅广播发射机的一些特点,然后分析了当前中波数字调幅广播发射机较为常见的故障以及产生的原因,最后提出了相应的解决方案。
An important device that has a crucial impact on broadcast transmission is a broadcast transmitter. For broadcast transmission, at present, the digital broadcast AM technology is the core technology of broadcast transmission and also an important factor affecting broadcast transmission. However, in the process of using AM digital amplitude modulation technology, there often exist some faults, which will bring some distress to the broadcast transmission. In order to ensure the normal operation of the broadcast transmitter, it is necessary to grasp the causes of the occurrence of some frequently-occurring faults and formulate the corresponding countermeasures. In this paper, the author first introduced some characteristics of AM wave AM transmitters, and then analyzed the more common faults and the causes of AM wave AM transmitters. Finally, the corresponding solutions were proposed.
