short mark, dot or "dit" (·) — "dot duration" is one time unit long
longer mark, dash or "dah" (–) — three time units long
inter-element gap between the dots and dashes within a character — one dot duration or one unit long
short gap (between letters) — three time units long
medium gap (between words) — seven time units long[1]
