中波广播发射台信号源系统组成架构与常见故障维修

The Composition Structure and Common Fault Maintenance of Signal Source System of Medium Wave Broadcasting Transmitting Station

中波广播发射台信号源系统是中波广播发射系统的重要组成部分,主要对广播节目信号进行接收和处理,同时产生同步广播所需的同步激励信号,其工作的稳定与否直接影响着整个发射系统的发射质量。基于此,对中波广播发射台信号源系统的组成架构、工作原理以及常见故障维修进行详细论述。

The signal source system of the medium-wave broadcasting transmitting station is an important part of the medium-wave broadcasting transmitting system.It mainly receives and processes the broadcast program signals,and at the same time generates the synchronous excitation signal required for the synchronous broadcasting.The stability of its operation directly affects the entire system.The launch quality of the launch system.Based on this,the composition structure,working principle and common fault maintenance of the signal source system of the medium wave broadcasting transmitting station are discussed in detail.
