channel demultiplexer meaning in Chinese

多路信号分离器

It consists of two parts : channel modulator ' s controlling system and the receiver ' s controlling system , including the interface designing of the demultiplexer , the controlling of the channel demultiplexer , if modulator , tuner , the setting and transmitting of the system parameters , and the real - time monitoring of the whole system , etc . based on the descriptions of the scheme of bdb - t and the principles of controlling circuits , this paper presents the hardware and software designing methods of the controlling circuits , and realizes a powerful , multifunctional and reliable controlling system which can automatically record the operational states of the system and communicate with other personal computers through a rs - 232 serial interface
控制系统是实现整个传输系统的关键部分，它分为信道调制器控制系统和接收机控制系统两大部分，其中包括了信道解复用器用户接口设计、对信道解复用器的控制、系统传输参数的设置与传送、中频调制器的配置、数字调谐器的配置，以及对整个系统的实时监控。本文在阐述了bdb - t方案及其各部分电路的控制原理的基础上，详细描述了控制系统的硬件电路设计和软件实现方法，实现了一套功能完善、性能稳定且具有自动记忆功能的控制系统，同时该系统通过rs - 232串行接口可以实现与计算机的串口通信。
