Morse code were also published in "QST", Another example occurred in 1966 when prisoner of war Jeremiah Denton, brought on television by his North Vietnamese captors, Morse-blinked the word "TORTURE". In these two cases, interpreters were available to understand those series of eye-blinks. International Morse code is composed of five elements: Morse code can be transmitted in a number of ways: originally as electrical pulses along a telegraph wire, 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 lamp or
Morse code Morse code Morse code is a character encoding scheme used in telecommunication that encodes text characters as standardized sequences of two different signal durations called "dots" and "dashes" or "dits" and "dahs". Morse code is named for Samuel F. B. Morse, an inventor of the telegraph. The International Morse Code encodes the ISO basic Latin alphabet, some extra Latin letters, the Arabic numerals and a small set of punctuation and procedural signals (prosigns). 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.
