In Morse Code, which letter is represented by a single dot?
"xz. Modern International Morse code (generally believed to have been developed by Alfred Vail based on English-language letter frequencies of the 1830s) encodes the most frequent letters with the shortest symbols; arranging the Morse alphabet into groups of letters that require equal amounts of time to transmit, and then sorting these groups in increasing order, yields e it san hurdm wgvlfbk opxcz jyq. Similar ideas are used in modern data-compression techniques such as Huffman coding. Letter frequency was used by other telegraph systems, such as the Murray Code. Letter frequencies, like word frequencies, tend to vary, both by writer and"
"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."

"in Morse code format, would normally be written something like this, where – represents dahs and · represents dits: Next is the exact conventional timing for this phrase, with = representing ""signal on"", and . representing ""signal off"", each for the time length of exactly one dit: Morse code is often spoken or written with ""dah"" for dashes, ""dit"" for dots located at the end of a character, and ""di"" for dots located at the beginning or internally within the character. Thus, the following Morse code sequence: is orally: ""Dah-dah dah-dah-dah di-dah-dit di-di-dit dit, Dah-di-dah-dit dah-dah-dah dah-di-dit dit"". There is"
"Telegraph code A telegraph code is one of the character encodings used to transmit information through telegraphy machines. The most famous such code is Morse code. Morse code can be transmitted and received with very simple electrical equipment, such as the electrical telegraph invented in 1816. Morse code represents each letter of the alphabet as a series of ""dots and dashes"" (short and long bursts of electronically-generated noise). The speed of sending is directly related to the length of the shortest (dot) element: a dash is three dots long, an inter-character gap is the same length (3 dots), and inter-word"

"Morse code for non-Latin alphabets This is a summary of the use of Morse code to represent alphabets other than Latin. The Greek Morse code alphabet is very similar to the Latin alphabet. It uses one extra letter for Greek letter ""Χ"" and does not use the codes for Latin letters ""J"", ""U"" and ""V"". The ""tonos"" is not transmitted in Morse code; the receiver can simply infer which vowels require one. The ""Greek diphthongs"" presented in the bottom three rows of the table are specified in old Greek Morse-code tables but they are never used in actual communication, the"

Morse code may be represented as a binary code, and that is what telegraph operators do when transmitting messages. Working from the above ITU definition and further defining a bit as a dot time, a Morse code sequence may be made from a combination of the following five-bit"

"was later made the standard by the International Telecommunication Union (ITU). Morse's original code specification, largely limited to use in the United States and Canada, became known as American Morse code or ""railroad code"". American Morse code is now seldom used except in historical re-enactments. In aviation, pilots use radio navigation aids. To ensure that the stations the pilots are using are serviceable, the stations transmit a set of identification letters (usually a two-to-five-letter version of the station name) in Morse code. Station identification letters are shown on air navigation charts. For example, the VOR-DME based at Vilo Acuña Airport"
"receiving Morse code when it is taught as a language that is heard, instead of one read from a page. To reflect the sounds of Morse code receivers, the operators began to vocalize a dot as ""dit"", and a dash as ""dah"". Dots which are not the final element of a character became vocalized as ""di"". For example, the letter ""c"" was then vocalized as ""dah-di-dah-dit"". Morse code was sometimes facetiously known as ""iddy-umpty"", and a dash as ""umpty"", leading to the word ""umpteen"". The Morse code, as it is used internationally today, was derived from a much refined proposal"
"For instance, the international code has only two symbols, dots and dashes, but the American code has several lengths of dash. There is a distinction between ""L"" () and ""T"" (). Also, in the international code the space between symbols within a character is always the same, but American Morse has two different spaces. The letters ""S"" (), ""C"" (), and ""R"" () all consist of three dots, but the timing is different in each case. A frequently quoted, but possibly apocryphal, story from the historical period concerns the similarity of ""L"" and ""T"" in the American code. A company"
"used by convention, but some prosigns have multiple forms in common use. Many Morse code prosigns do not have written or printed textual character representations in the original source information, even if they do represent characters in other contexts. For example, when embedded in text the Morse code sequence represents the ""double hyphen"" character (normally ""="", but also ""– –""). When the same code appears alone it indicates the action of spacing down two lines on a page in order to create the white space indicating the start of a new paragraph or new section in a message heading.

"The duration of a dash is three times the duration of a dot. Each dot or dash within a character is followed by period of signal absence, called a ""space"", equal to the dot duration. The letters of a word are separated by a space of duration equal to three dots, and the words are separated by a space equal to seven dots. To increase the efficiency of encoding, Morse code was designed so that the length of each symbol is approximately inverse to the frequency of occurrence in text of the English language character that it represents. Thus the"
