Baloney. By this definition, OOK Morse is a "time-multiplexed"
system, eh?

Why not just Google this: define: multiplexing

Then try this: define: time multiplexed. And the answer is, "Huh?"

What you mean is that the LEDs are pulsed at some rate and/or duty
cycle. I wouldn't call this, "multiplexing."

Took the words right out of my mouth, Roy. I almost asked that in the
previous post.

Time Domain Multiplexing is where two or more signals share one data
pipe. Under TDM each signal is allocated one domain. Each domain is sent
in sequence. At the other end each domain is isolated and combined with
other domains elements from the same source. i.e. a, b, c fragmented and
sent as a1, b1 , c1, a2, b2, c2, a3, b3, c3 received and defragmented as
a, b, c. Commonly used to sent telephone conversations and internet
packets over copper wires and radio.
