Question
Which of the following describes Baudot code?
Answer Options
- A) A 7-bit code with start, stop, and parity bits
- B) A code using error detection and correction
- C) A 5-bit code with additional start and stop bits
- D) A code using SELCAL and LISTEN
Correct Answer: C
Explanation
Baudot code, historically used for telegraphy and still used for traditional RTTY (Radio Teletype), is a character encoding standard known for its simplicity and lack of redundancy.
Baudot code uses only 5 data bits to represent a character. Because 5 bits only allow 2^5=32 unique characters, it uses a shift mechanism to represent both letters and figures (numbers/symbols). When transmitted, the 5 data bits are framed by additional start and stop bits for synchronization, resulting in a low-speed, robust digital mode.
