Hog-Morse 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
Morse code and Channel Coding comparisons, the word "PARIS" is used to determine Morse Code's properties because it has an even number of dots and dashes. Morse Code, when transmitted essentially, creates an AM signal (even in on/off keying mode), assumptions about signal can be made with respect to similarly timed RTTY signalling. Because Morse code transmissions employ an on-off keyed radio signal, it requires less complex transmission equipment than other forms of radio communication. Morse code also requires less signal bandwidth than voice communication, typically , compared to the roughly 2400 Hz used by single-sideband voice, although at a lower data
