What is the principle of Morse code?

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. He signed an agreement with Alfred Weil to help him make more practical equipment. Alfred Weil conceived a scheme in which each character and punctuation can be sent independently of each other through dots, strokes 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. It consists of two basic signals and different intervals: short point signal. , read "Di"; Keep a long signal for a certain time, tick "-"and read "A". Interval time: down,1t; ; Answer, 3t; Tick-tock,1t; ; Between letters, 3t; Between the lines, 5t. Within a letter or number, the interval between dot and dash should be 2t. The interval between letters (numbers) and letters (numbers) is 7t.

In China's telegraph communication, each Chinese character has four last bits of information. "Short code" cannot be mixed with code! Amateur radio communication does not use "short code"!
