But he lacks relevant professional knowledge. He signed an agreement with Alfred Weil to help him make more practical equipment. Weil conceived a scheme in which each character and punctuation can be sent independently of each other through dots, dashes and pauses in the middle. They agreed to include this scheme of marking different symbols in Morse's patent. This is now known as American Morse code, which was used to transmit the world's first telegram. This code can be transmitted by a smooth-pitched, intermittent radio signal, usually called continuous wave, abbreviated as CW. It can be an electronic pulse in a telegraph line or a mechanical or visual signal (such as a flash). Generally speaking, any coding method that can express written words with variable-length signals can be called Morse code. But now this term is only used to refer to two kinds of Morse code representing English letters and symbols: American Morse code is used in cable telegraph communication system; The international Morse code still in use today only uses dots and dashes (no pause). The telegraph company charges according to the length of the letter to be sent. The commercial code carefully designed a set of five characters to send as a word. For example: byoxo ("Do you want to climb out?"
Morse code of the above speed. Although the traditional telegraph key is still used by many enthusiasts, semi-automatic and fully automatic electronic keys have been widely used today. Computer software is also often used to generate and decode Morse code radio signals. There are two kinds of "symbols" for time control and representation: dot and dash, or Dit and Dah. The length of the point determines the sending speed as the sending time reference. The following is a schematic diagram of time control:-* * * *-* * m o r s c o d e here,-stands for row. Representative point. This is the exact sending time of the above message. Indicates that the signal is no, each is the length of a point): = =. = = = = = ... = = = = = = = = = = = = = = ... The interval between points and strokes is the length of a point; The interval between characters is the length of three points; The interval between words is the length of seven points. Beginners are often taught to pronounce short, short and fast braille, exaggerating the interval between symbols and words. Comparatively speaking, this method is easier to learn. People who are familiar with Morse code often speak or spell like this (in which "long sound /Dah" is pronounced as "awe"):-*-* * * *-* * * Dah Dah Didi Didi dit < script language = JavaScript > & lt/Script & gt； DahDah DahDiDit。 Letters, numbers, punctuation and the same symbols
The earliest Morse code was dots and dashes representing numbers. Numbers correspond to words. You need to look up a code table to know the numbers corresponding to each word. You can click, stroke and pause with the electric keys. Although Morse invented the telegraph, he lacked relevant professional knowledge.
