When we think of morse code in movies, it is usually a sound that lets us know someone is sending a secret message or code.
What’s Morse Code? Morse code is a system that uses dots and dashes to relay or send messages. A dot looks like a period, and a dash is a long horizontal line.
A dot is called a dit, and a dash is called a dah. Different combinations of dits and dahs represent each letter in the english language. They can be strung together to create words and sentences.
Timing of the Sounds
The length of each symbol is related to the length of 1 dit:
A dit is 1 unit of sound.
When switching between dits and/or dahs in the same letter, you leave one unit of silence.
A dah is the length of 3 units (3 dits).
To move to the next letter, you insert a pause of 3 units. To move to the next word, you insert a pause of 7 units. You can think of the pause like a space when you type.
