Correction to my last. For those that are interested

International Morse code is
composed of five elements:
1. short mark, dot or "dit" (·) — "dot duration" is one time unit long
2. longer mark, dash or "dah" (–) — three time units long
3. inter-element gap between the dots and dashes within a character —
one dot duration or one unit long
4. short gap (between letters) — three time units long
5. medium gap (between words) — seven time units long[1]
Morse code can be transmitted in
a number of ways: originally as electrical pulses along a telegraphwire, but
also as an audio tone, a radio signal with short and long tones, or
as a mechanical, audible or visual signal (e.g. a flashing light) using devices
like an Aldis
lampor a heliograph, a common flashlight, or even a car horn. Some
mine rescues have used pulling on a rope - a short pull for a dot and a long
pull for a dash.
Morse code is transmitted using
just two states (on and off). Historians have called it the first digitalcode.
Strictly speaking it is not binary, as there are five fundamental
elements (see quinary).
However, this does not mean Morse code cannot be represented as a binary code.
In an abstract sense, this is the function that telegraph operators perform
when transmitting messages. Working from the above definitions and further
defining a "unit" as a bit, we can visualize any Morse code sequence as a
combination of
the following five elements:
1. short mark, dot or "dit" (·) — 1
2. longer mark, dash or "dah" (–) — 111
3. intra-character gap (between the dots and dashes within a character)
— 0
4. short gap (between letters) — 000
5. medium gap (between words) — 0000000
Note that this method assumes
that dits and dahs are always separated by dot duration gaps, and that gaps are
always separated by dits and dahs.
