"Morse is dah-dah-di-dah, which can be memorized by the phrase ""God save the Queen"", and the Morse for ""F"" is di-di-dah-dit, which can be memorized as ""Did she like it."" A well-known Morse code rhythm from the Second World War period derives from Beethoven's Fifth Symphony, the opening phrase of which was regularly played at the beginning of BBC broadcasts. The timing of the notes corresponds to the Morse for ""V"", di-di-di-dah, understood as ""V for Victory"" (as well as the Roman numeral for the number five). Prosigns for Morse code are special (usually) unwritten procedural signals or symbols that"
"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."

"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"

"Two-out-of-five code In telecommunication, a two-out-of-five code is an m of n code that provides exactly ten possible combinations, and thus is popular for representing decimal digits using five bits. There are ways to assign weights to each bit such that the set bits sum to the desired value, with an exception for zero. According to Federal Standard 1037C: The weights give a unique encoding for most digits, but allow two encodings for 3: 0+3 or 10010 and 1+2 or 01100. The former is used to encode the digit 3, and the latter is used to represent the otherwise unrepresentable"

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"".
