浅谈全固态PDM发射机信号监听系统电源部分理论设计分析

中波发射台为做好安全播出工作，对全固态PDM发射机输出的高频信号采取监听、监测，信号监听系统扮演着重要的角色。我台技术人员自行设计的信号监听系统成功投入使用，它具有信号源输入显示、高频信号输出显示、音频故障报警、自动切换、外接监听音箱显示控制等功能，可满足中波转播台播出信号监听监测的需要，本文着重介绍该系统电源部分理论设计分析。

On the Theoretical Design and Analysis of the Power Supply of the Whole Solid State PDM Transmitter Signal Monitoring System

In order to do a good job in security broadcast,the medium wave station is monitoring the high frequency signal output of all solid state PDM transmitter. Signal monitoring system plays an important role in the whole launch system. The signal monitoring system designed by our technical staff has been successfully put into use. Display input signal source with the system,high frequency signal output display,audio fault alarm,automatic switching,external monitors display control functions,make the medium wave broadcasting station monitor broadcast signal . This paper focuses on the theoretical design and analysis of the power supply of the system.
