Morse code. a brief description of

Morse code is a special way of encoding various linguistic signs - letters, punctuation marks, and also numbers by means of sound signals. Two types of signals are used: short indicates a point, long - a dash. Originally Morse code was used in the telegraph.

The Morse code was invented by the American Samuel Morse in 1838. The idea to create a system for transmitting information was visited by Samuel after the publication of M. Faraday's books, as well as the experiments of Schilling. Morse worked on his offspring for more than three years, until his work was unsuccessful. The first signal was sent to them on a wire, the length of which was 1,700 feet. Experiments interested Steve Vale, who also funded the experiments of Morse. It was thanks to him that on May 27, 1844, the first related message was sent, the text of which read: "Marvelous are your deeds, Lord."

Of course, during the time the system changed and improved. The final version was proposed in 1939. It is interesting that Morse code itself began to be called only with the beginning of the First World War. It was at that time that its "continental" version became widespread.

Like any sign system, the Morse code has both advantages and disadvantages. Among the advantages of this code can be identified such as the ability to record and play back signals with the help of simple devices, the possibility of manual encoding, as well as high immunity from interference, provided that the message is received by ear even if there is strong radio interference.

As for the shortcomings, they include the low speed of telegraphy, the code itself is of little use for letter printing, and moreover, the transfer of one such sign requires an average of about 9-10 elementary parcels, which is quite uneconomical.

The most famous signal that transmits the Morse code is the SOS. This signal can be given only in situations where there is an imminent threat to the lives of people or a vessel at sea. Despite the fact that the SOS signal is interpreted by many as "Save our souls", or, according to some, "Save our ship" (save our ship), this is absolutely not the case. This type of signal was chosen only because of its simplicity: three points, then three dashes and again three points, which is fairly easy to remember.

How to remember all the signs transmitted with the Morse code? Songs are one of the most famous and simple ways to learn Morse code.

Songs are a rhythmic pronunciation of various sets of dashes and dots. It should be noted that syllables, which include such vowels as "a", "s" or "o", denote a dash, and the remaining syllables, as well as the sound "ay" - a point.

For example, the letter "and", consisting of two points, is memorized with the help of the melody of the word "i-di", and the letter "k" (-.-) - using the phrase "kaaak-ta-taaak".

To date, there are many different programs with which you can study the Morse code, synthesize messages, encode and decode information using the alphabet, and also practice receiving and sending Morse signals with light.

Despite the fact that in our time there are a lot of new systems and codes for information transfer, the Morse code is still popular among radio amateurs.
