Research On Multiplex Data Flow Test System

The article carries out research on multiplexing, test system and design model of multiplex data flow. Multiplexing means that a technique used in communications and input/output operations for transmitting a number of separate signals simultaneously over a single channel or line. To maintain the integrity of each signal on the channel, multiplexing can separate the signals by time, space, or frequency.On time division multiplexing (TDM), wave division multiplexing (WDM), and frequency division multiplexing (FDW), serial transmission, asynchronous transmission, transaction mix, or design of test system of multiplex data flow, the article has already been fully researched. Of course this part is very important.What main function can this system of multiplex dataflow perform?Firstly, the system cannot only test rapidly for baud rate and parity checking of date, but also control input/output date flow.Secondly, the system has a special function of funneling several different streams of data over a common communications line. This point is this part is chief..Finally, the index of data flow's performance can be displayed.
