After the Finger Alphabet and Flag Semaphore, I have now also revised the Morse Code for posters! The infographics is available as a poster at Posterlounge (also via eBay!) as well as printed on beautiful cards, mugs, bags, shirts, cushions, towels, blankets, cases, stickers and many other products at Redbubble and Søciety6.
Morse Code is used as a code for telegraphic transmission of letters, digits and other characters. Letters are represented by combining a time scheme (long, short), according to the pattern of a signal being switched on and off. The Morse code is transmitted as a sound signal or radio signal, electrically (e.g. morse key), mechanically (e.g. knocking) or optically (e.g. flashing). Theoretically, any that can be used to represent two different states in a time-variable manner is suitable. The transmission method itself is called Morse telegraphy.
Samuel Morse invented a simple code for 10 digits, which could be translated into letters and words using a table, in 1837, and his employee Alfred Lewis Vail developed the first code with letters in 1838. These letters were coded with three different lengths and pauses, and used as “Morse Landline Code” by American railroads and telegraph companies since 1844. Friedrich Clemens Gerke simplified the code in 1848, and after minor changes, this code was standardized at the International Telegraph Congress in Paris in 1865 and is reknown as “International Morse Code”.
The Morse Code is part of my series of alphabets which includes Finger Alphabet, Flag Semaphore and Braille Alphabet.
