中波全固态数字调制发射机主要是运用数字技术进行调幅的广播的发射机。在发射机的运行中,主要使用的是微功耗数字集成电路。这种发射机采用整机使用晶体管,这样就缩小了发射机的体积,从而减少了发射机的运营成本,大大提高了经济效益。中波广播发射机有完整的系统,在控制、检测、电路保护中,有很强的稳定性。根据实际工作中的操作经验,阐述了中波广播发射机的数字调制原理和方法,为实现中波广播发射机的技术提升提供一定的现实依据。
Medium wave all solid state digital modulation transmitter is mainly the use of digital technology for AM transmitter. In the operation of the transmitter, the main use of micro-power digital integrated circuits. The transmitter uses the whole machine using transistors, thus reducing the size of the transmitter, thus reducing the transmitter’s operating costs, greatly improving economic efficiency. Medium wave broadcast transmitter has a complete system, in the control, detection, circuit protection, there is a strong stability. According to the operational experience in practical work, the principle and method of digital modulation of medium wave broadcast transmitter are expounded, which provides some realistic basis for the technical improvement of medium wave broadcast transmitter.
