Well, all of this contradicts my understanding of the
term. As I see it multiplexing is encoding two or more
data streams within ONE channel so looking at multiple
channels each containing one data stream can never be
multiplexing. Multiplexing may well become involved in
such applications as remote operation of a microscope.
