Hi!

Take a look at the wikipedia. If you do "one at a time" at 100Hz, you
can claim it is time-domain multiplex. But we are plain switching the
cameras. It takes second (or so) to setup the pipeline.

This is not multiplex.

The functionality is still the same, isn't it? Does it change what it is if
the frequency might be 100 Hz or 0,01 Hz?

Well. In your living your you can have a switch, which is switch at
much less than 0.01Hz. You can also have a dimmer, which is a PWM,
which is switch at 100Hz or so. So yes, I'd say switch and mux are
different things.

Light switches are mostly on/off switches. It'd be interesting to have a
light switch that you could use to light either of the light bulbs in a room
but not to switch both of them on at the same time. Or off... :-)

I wonder if everyone would be happy with a statement saying that it's a
on / on switch which is used to implement a multiplexer?

I believe the difference is the timescale. If it switches "slow" it is
a switch. If it switches fast, it is a dimmer, mux, or something....

Anyway, someone else was faster, so they get to name their creation...
