The telegraph, as says our colleague José Geraldo Padua- PY2JGP, "is the art of transmitting coded messages through a specific device called the telegraph." The different sounds produced to manipulate the telegraph are able to offer a perfect understanding to the human ear. The system is represented by international convention signals and composed of larger signals ( traces ) or smaller ( points) on each letter and the pace is what will differentiate between them. As the signals form the sound, each letter has its distinctive sound, making it unmistakable with another letter or number, because the sound differs, so we briefly telegraphy, as a sound language and rhythm, making it a coded language. | |
