Morse-code definitions

Any of several codes used for transmitting messages in which letters of the alphabet and numbers are represented by various sequences of dots and dashes or short and long signals, especially the international Morse code.

A code developed by Samuel Morse used for transmitting messages in which letters of the alphabet and numbers are represented by various sequences of written dots and dashes, or short and long signals such as electric tones or voltages. Morse code was used extensively in telegraphy. In a format that has been standardized for international use, it is still sometimes used for long distance radio communication.

The first widely accepted standard coding scheme for digital data communications. Morse code was invented by Samuel Morse sometime prior to 1844 for use with the electric telegraph. Friedrich Clemens Gerke invented the International Morse Code in 1848 out of necessity, as some of the spaces in letters created difficulty in radiotelegraphy. International Morse code was standardized by the International Telegraph Union (ITU) in 1865 and was widely used in radiotelegraphy through the early twentieth century. Morse code was the primary communication code for many years, until Emile Baudot invented the Baudot Distributor in the 1870s. International Morse code remains widely used by amateur radio operators, or hams, although proficiency is no longer required. Morse code uses series of short and long marks in the form of dots (short marks known as dits to radio operators) and dashes (long marks, or dahs), with spaces between them, to represent letters, numbers, punctuation marks, and procedural signals (prosigns). The length of the spaces varies, with a short space between dots and dashes within a character, a longer space between characters, an even longer space between words, and a yet longer space between sentences. In order to speed transmission, the fewest number of dots and dashes represent commonly used letters (e.g., E is ·,T is --, A is · --). Commonly used words are abbreviated (e.g., Calling is abbreviated CG, or -- · -- · -- -- ·, as are commonly used phrases (e.g., Love and Kisses is abbreviated 88, or -- -- -- · · --- -- · ·.Table M-1 provides the International Morse Code for English letters, numbers, and select punctuation marks and prosigns. Note: The @ sign, a combination of a and c, was added in 2004 in order that telegraphers could send e-mail addresses.There are extensions to International Morse Code to accommodate letters with diacritical marks used in non-English alphabets. See also dash, dot, ham, ITU, and telegraph.

A character code invented by Samuel Morse that is represented by the duration of a single tone. Written as dots, dashes and spaces, the first Morse code message was sent in 1844 over a newly constructed telegraph line between Baltimore and Washington. In World War II, Morse code was sent by light signals. A variation of the original was made by Friedrich Gerke in 1848, which evolved into the International Morse Code.Dits and Dahs - Actually Hear Them!The code was based on English; E and T being the most frequently used letters, hence one dot was assigned to E and one dash for T (see table below). Dots and dashes are vocalized as "dit" and "dah," and the timing is one dit between each dit and dah, three dits between letters and seven dits between words.

Given the secret message at the same time "I just saved a bunch of money on my car insurance," the Morse code operator tapped all the words to his colleague across the stage before the young texter could finish typing the sentence.
