This article mainly introduces what the Morse code in the computer is, which is very detailed and has a certain reference value. Interested friends must finish reading it!

Morse code (Morse code) is a time-switching signal code that expresses different English letters, numbers and punctuation in different order; its code includes five types: pauses between dots, strokes, dots and strokes, short pauses between each character, moderate pauses between each word, and long pauses between sentences.

Morse code, also known as Morse code, is a kind of time-on and off signal code, which expresses different English letters, numbers and punctuation marks through different arrangement order. It was invented in 1837 and is an early form of digital communication. Unlike modern digital communications, Morse code uses only zero and one or two binary codes. Its code includes five types: a short dot signal, a Di that keeps a long signal for a certain period of time, a Da that indicates a pause between a dot and a stroke, a moderate pause between each word, and a long pause between sentences.

The representation of Morse Code

In fact, there are two kinds of "symbols" that are used to represent characters: strokes and dots, or Dah and Dit, respectively, or long and short. The speed of transmission is determined by the length of the point, and is used as a reference for the time of transmission. The following is an illustration of time control:

Morsecode:

Here, "-" means to draw, "." It represents a point. This is the exact time when the above message was sent ("=" means the signal has, "." Represents none of the signals, each of which is the length of a point:

=. =. = =. =. = =. = =

A stroke is usually the length of three points; the interval between dots is the length of one point; the interval between characters is the length of three points; and the interval between words is the length of seven points. At the beginning, beginners are generally taught to send short, short and fast characters, symbols and words that are exaggerated. Comparatively speaking, this way is easier to learn.

People who are familiar with Morse often talk or spell like this [in which "Dah" sounds like "awe":

DahDahDahDahDahDiDahDitDiDiDitDit, DahDiDahDitDahDahDahDahDiDiDit.

Special symbol

These are some combinations of dots with special significance. They are concatenated by two-letter Morse codes, which saves the interval time necessary to send them as two letters normally.

AR:-(stop, message ends)

AS:-(wait)

KRV-- (invite to send a signal) (usually follow AR, meaning "your turn")

SK:-(termination, end of contact)

BT:--(delimiter)

-(I will resend the last word)

(again)

(error)

Morse code application

Morse code is simple and clear, with little ambiguity, and the code is mainly represented by two characters: ".", "-", one long and one short, which is widely used in many cases, such as sending a distress signal. In the movie "the Wind", the Moore code is sewn on the clothes to spread the news. Cartoon "famous Detective Conan" in the "reasoning duel, the new vs Chong Yazhu" (tv511) is the use of this method.

When using the Moore code light to call for help, it is defined that the light is "-" and the light is short "." then various messages, such as distress messages, can be sent through the switch of the flashlight.

If the light is displayed according to the law of "short light and dark long light and dark light", then it means the distress signal SOS.

Because the mole code of SOS is: -, you can encode the light according to the above. This code is actually very simple, three short, three long, three short.
