Telegraph code and sentence gaps should be 5 or 7 dots long (change from earlier standard – 5 dots). The speed of sending is also referred to as words per minute, and is classically based on the 'paris' formula - as 'paris' is considered to be an average length word. See main article on Morse Code. Morse code can even be used to transmit Chinese characters. There already existed dictionaries which numbered the Chinese characters. It is simply a case of sending the numbers by Morse Code, and these numbers are then looked up in the dictionary at the receiving end. In
Telegraph code 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
