It is a        AK>> ternary code. In binary code it is not necessary because every        AK>> byte has 8 bits.               AS> I did not realise it. I thought that decyphering did not requier        AS> character separators.              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> See also:        AS> Is Morse Code binary, ternary or quinary?               AS> https://cs.stackexchange.com/questions/39920/is-morse-code-       inary-ternary-or-quinary              IMHO it is writen too much there on a simple subject.                     Bye, Anton!       Alexander Koryagin       english_tutor 2021              ---         * Origin: nntp://news.fidonet.fi (2:221/6.0)       SEEN-BY: 1/19 123 16/0 19/10 90/1 105/81 120/340 123/130 131 129/305       SEEN-BY: 203/0 221/1 6 360 226/30 227/114 702 229/101 424 426 664       SEEN-BY: 229/1016 1017 240/1120 2100 5138 5411 5824 5832 5853 249/206       SEEN-BY: 249/317 261/38 280/5003 282/1038 317/3 320/119 219 319 322/0       SEEN-BY: 322/757 335/364 342/200 423/81 640/1384 2454/119 4500/1 5020/1042       PATH: 221/6 1 320/219 240/5832 229/426           |
