Description
Morse code is a telecommunications method for encoding text characters as standardized sequences of two different signal durations known as dots and dashes, or dits and dahs. Morse code is named after Samuel Morse, one of the telegraph's inventors.
International Morse Code encodes the 26 basic Latin letters A through Z, one accented Latin letter (é), the Arabic numerals, and a small set of punctuation and procedural signals (prosigns). Upper and lower case letters are not distinguished. Each Morse code symbol is formed up of a series of dits and dahs. In Morse code transmission, the dit duration is the basic unit of time measurement. The duration of a dah is three times that of a dit. Each dit or dah within an encoded character is followed by a signal absence, known as a space, that is equal to the dit duration. A space equal to three dits separates the letters of a word, and a space equal to seven dits separates words.
American Morse Code, also known as Railroad Morse, is the modern name for the original Morse Code developed by Samuel Morse and Alfred Vail for their electric telegraph in the mid-1840s. The qualifier "American" was added because, after the majority of the rest of the world adopted "International Morse Code," the companies that continued to use the original Morse Code were mostly based in the United States. American Morse is now nearly extinct; it is most commonly seen in American railroad museums and Civil War reenactments, and "Morse Code" today almost always refers to the International Morse that supplanted American Morse.
