World Morse code day

Morse code day

Every year 27 april is celebrated as Morse code day to commemorate the birthday of Samuel Morse. It's a day to recognize the first step in electronic communications that started with a few simple dots and dashes, and over the years has evolved into us being able to sit in a park and download a funny video or talk with nearly anyone in the world.

Samuel Morse

He was an American painter who born in Massachusetts 27 april 1791.
After having established his reputation as a portrait painter, in his middle age Morse contributed to the invention of a single-wire telegraph system based on European telegraphs. He was a co-developer of the Morse codeand helped to develop the commercial use of telegraphy

What is Morse code

Morse code is the method of transmitting information in the series of of on off tones, lights and clicks that can be directly understood by skilled listener without any special equipment. It is named after Inventor Samuel Morse

Each Morse code symbol represents either a text character (letter or numeral) or a prosign and is represented by a unique sequence of dots and dashes. The dot duration is the basic unit of time measurement in code transmission. The duration of a dash is three times the duration of a dot. Each dot or dash is followed by a short silence, equal to the dot duration. The letters of a word are separated by a space equal to three dots (one dash), and the words are separated by a space equal to seven dots.[1] To increase the speed of the communication, the code was designed so that the length of each character in Morse is approximately inverse to its frequency of occurrence in English. Thus the most common letter in English, the letter "E", has the shortest code, a single dot.

SOS, the standard emergency signal, is a Morse code prosign
In an emergency, Morse code can be sent by improvised methods that can be easily "keyed" on and off, making it one of the simplest and most versatile methods of telecommunication. The most common distress signal is SOS – three dots, three dashes, and three dots – internationally
