What is Morse Code?
Morse code is a character encoding system that represents letters, numbers, and punctuation as sequences of short signals (dots/dits) and long signals (dashes/dahs). Developed by Samuel Morse and Alfred Vail in the 1830s for use with the electric telegraph, it became the primary method of long-distance communication for over a century.
Despite being largely replaced by modern digital communications, Morse code remains relevant in amateur radio, aviation emergency signals, accessibility applications, and as an educational tool for understanding concepts like encoding and signal processing.
How Morse Code Works
- Dot (dit) — A short signal, the basic time unit
- Dash (dah) — A long signal, three times the length of a dot
- Letter gap — Silence equal to three dots between letters
- Word gap — Silence equal to seven dots between words
