Morse code is a digital communication signal. It can be transmitted in many different ways, including visible light, radio waves and electrical pulses. A system for representing letters of the alphabet, numerals, and punctuation marks by an arrangement of dots, dashes, and spaces.
Not only is Morse Code a grand-daddy of communication messaging. It also is a beautiful thing when noted in it’s visual format.
Each letter of the alphabet and 10 numerals is represented by a visual sequence of dots and dashes. Which used in telecommunications is then transmitted as two different signal durations called dots and dashes or dits and dahs. A dash being equal in length to 3 dots.
