Do the detectives have any research on Morse Code 100

Morse code was invented in 1837 by the controversial inventor Samuel Morse or Alfeld Weir.

Morse code is a time-on-break signal** that expresses different letters, numbers, and punctuation marks in different sequences.

Morse code was an early form of digital communication, but unlike modern binary, which uses only zeros and one or two states, it includes five types: dots, strokes, pauses between dots and strokes, short pauses between each character, medium pauses between words, and long pauses between sentences.

Morse Alphabet was invented in 1837 by an American, Samuel Finley Breese Morse. It consists of dot(.).) dash (-) symbols.

Morse code played an important role in early radio and was a must-know for every radio communicator. Due to the advancement of communication signal technology, countries have stopped using Morse code in 1999, but because it occupies the least bandwidth, and has a technical and artistic characteristics, it has a wide range of applications in practical life. There are many types of passwords used in warfare, such as:

Two-point, three-point, quarter-code, Poleife code, rotary wheel encryption, multi-code encryption, Hill code, Ettebashi code, etc.

Stupid, you said it was Morse yourself.

Morse code is an early form of digital communication, but unlike modern binary systems, which use only zeros and one or two states, Morse code includes five types: dots, strokes, pauses between dots and strokes, short pauses between each character, medium pauses between words, and long pauses between sentences.

Morse Code It consists of two basic signals and different intervals:

Short dot signal "·" read "drop" (di);

Hold a long signal for a certain period of time" —" reads "click" (da).

If the light is displayed according to the rule of "short bright, dark, short bright, dark, dark, long, dark

When Morse invented the code, it can be said that he racked his brains and put a lot of effort into it. He made a lot of statistics on the characters commonly used in newspapers and periodicals, and personally went to the printing house to consult the printing workers, in order to assign the simplest code combinations to the most commonly used English letters in daily life, "t" is represented by "-", and "z", "q", "j" and other less commonly used English letters are represented by more complex code combinations. In order to make it easier to remember, the code of 10 Arabic numerals is arranged in a regular way, such as "1" with "--2" with "sale--- representation.

In addition to the strict rules on the combination of "dot" and "stroke" for each character, the length of dot and stroke and the size of the interval also have a certain time ratio. The length of time between the point and the stroke is one to three (that is, when the report is sent, the time of pressing the electric key to make the "stroke" is equivalent to the time of three "points"); The interval between points and points, points and strokes, and strokes is equal to the time of a point; The interval between each character is equal to the time of three "dots"; The interval between words is the time of five "dots".

For example, the time to send a "point" is one millisecond (thousandths of a second), and the time to send a "stroke" is three milliseconds; Leave a three-millisecond interval between characters; There is a five-millisecond pause between words. These are the laws of Morse code.

Morse code was invented by the American Morse in 1844.

The earliest morse codes were dots and strokes that represented numbers. Numbers correspond to words, and you need to find a ** table to know the number corresponding to each word. With an electric key, you can hit the dots, strokes, and pauses in between.
