| Abstract: | The twenty channel stereo digital transmission system and its principle are introduced. The functions of this transmission system, the transmitting unit and receiving unit, 34 Mb/s multiplexer and demultiplexer in the system and the circuit of frame synchronization are analyzed. The testing results show that the system, which has been used in practical environment, has many stereo channels, good compatibility and superb performances. |
