Without a special signal all the Morse dots/dashes will merge into a
continuous stream. So, a pause in Morse code is also a signal. We have short
beep, long beep, and a long pause.

Just for fun, we can invent a coding system using pause signals. For instance,

A short beep - is a separator

Between separators can be:
one second pause implies 1
two seconds pause implies 2
three seconds pause implies 3
....
nine seconds pause implies 9
ten seconds pause implies 0

And we have very a silent variant of "Morse" code for digits transfer. ;-)

 AS> https://cs.stackexchange.com/questions/39920/is-morse-code-

IMHO it is writen too much there on a simple subject.


Bye, Anton!
