Think about microprocessors. For lack of space, at some places a cyclic multiplexer converts parallel to serial data. After the serial transmission a cyclic demultiplexer converts the serial data back into parallel data...
Circuit diagram multiplexer-demultiplexer. |
Although a multiplexer works here in conjunction with a demultiplexer, they are usually referred to as multiplexer units...
Illustration switch analogy multiplexer-demultiplexer. |
In telecommunications, such as telephone systems or satellite communication, connections over long distances are required and therefore precious. Also here you find multiplexers and demultiplexers.
However, in telecommunications often analog signals are processed. Until now you have discussed multiplexer that handle only digital signals...
In the next experiments, you meet a new component, with which you can process analog signals in a multiplexer...
