Morse code [SEP] Introduction
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called "dots" and "dashes" or "dits" and "dahs". Morse code is named after Samuel Morse, an inventor of the telegraph. The International Morse Code encodes the 26 English letters A through Z, some non-English letters, the Arabic numerals and a small set of punctuation and procedural signals (prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of dots and dashes. The dot duration is the basic unit of time measurement in Morse code transmission.
