1. A design of MPEG-2 system multiplexor is proposed.

2. An easy-to-realize scheme of MPEG-2 program stream multiplexor is proposed.

3. Type of Multiplexor that combines multiple channels onto a single transmission medium in such a way that all the individual channels can be simultaneously active.

4. In order to satisfy the special requirement of synchronic serial communication protocol between multiplexor and synchronic data terminal, we design the special communication chip with CPLD.

5. In addition, on the basis of applying SCMAIC, some function modules such as multiplexor, non-linear encoder and non-linear decoder, which are used in this ternary PCM system, are designed.

6. The paper introduces theory and design of high density resistivity prospecting testing sys-tem, especially the programming multiplexor in its key components.

7. In keeping with the Reactor pattern, a Selector class is a multiplexor of Channels.

8. The left and right channels are combined to one digital data string via a multiplexor.
