浅谈地面数字广播电视发送系统的设立

Discussion on establishment of the terrestrial digital radio and television transmission systems

在原有模拟发射台站建立数字广播电视发送系统,应尽可能考虑使用原有的模拟电视发送系统设备和用户利用原有接收天线,尽量低的经济投入来开展地面数字广播电视。采用多工器完成RF功率合成、多频道放大器合成,可使地面数字广播电视使用现有的模拟广播电视发射天线。

The original analog fire stations set up digital broadcasting and TV transmission system, as far as possible to consider using the original analog TV system equipment and to the user using the original receiving antenna, low economic investment as far as possible in order to develop digital terrestrial broadcasting and television. Using multiplexer, multichannel amplifier complete RF power, can make the terrestrial digital broadcast television using an existing analog broadcasting and television transmitting antenna.
