If I search multiplexer in Google and start reading, I find sources that describe a multiplexer as a device that selects between several analog or digital signals, then outputs a single signal. For example, a multiplexer is described as kind of a switch, that just selects one of the input signals.

This seems like a form of multiplexer, but more generally, I always though a multiplexer combined the signals into a single signal then a demultiplexer separates the signals into the separate signals....

So, is a multiplexer just a switch (as defined in the beginning of the Wikipedia article)? Or, does a multiplexer mix signals (e.g., frequency division multiplexing)?

Sorry, I don't know what tags I should select.

    $\begingroup$ Can you provide a bit of context? There are different kinds of multiplexers for different application areas. $\endgroup$

  • $\begingroup$ I suppose referring to the integrated chips, but I was wondering in general, which maybe why I see the variation in definitions. $\endgroup$

  • $\begingroup$ OK, can I please ask you to have a look at this, especially the "See also" section and after that maybe edit your question with the bits that you feel are grey areas? $\endgroup$

  • $\begingroup$ @Ralff "Multiplexer" is a general term that is used in many contexts. For example, you can have TDM (time-division multiplexing) or FDM (frequency-division multiplexing). You still need to clarify what the context of your question is. $\endgroup$
