摩斯密码是如何工作的？
Understand the precise timing ratios, signal channels, and structural rules that make Morse code the world’s most resilient encoding system.
Standard ITU Timing Ratios
The 1 : 3 : 7 Spacing Rule
International Morse code relies on strict relative timing units rather than fixed clock speeds:
1 Unit
Dot (Dit)
Short signal duration
3 Units
Dash (Dah)
Exactly 3× dot length
3 Units
Letter Pause
Silence between letters
7 Units
Word Pause
Silence between words
Transmission Channels
Morse code can be transmitted through any medium capable of binary switching:
- Sound Tones: 600 Hz – 800 Hz audio beeps (ham radio CW)
- Light Signals: Flashlight, Aldis lamp, or beacon flashes
- Electrical Pulses: Telegraph line voltage pulses
- Tactile Taps: Physical tapping or vibration motors
Frequently Asked Questions
What is the timing ratio for dots and dashes in Morse code?
The fundamental timing ratio is 1:3. One dot equals 1 time unit, and one dash equals 3 time units. The space between elements within a letter is 1 unit, between letters is 3 units, and between words is 7 units.
How does Morse code differ from binary code?
Binary code uses two states (0 and 1) of fixed length. Morse code uses variable-length signal durations (short dit vs long dah) and relies on silent pauses of specific lengths to delimit characters and words.
