G8C04
Which of the following describes Baudot code?
- 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 (correct answer)
- D.A code using SELCAL and LISTEN
WhyBaudot code is a 5-bit code with additional start and stop bits. Baudot code represents each character with 5 data bits, supplemented by separate start and stop bits framing each character for synchronization, the scheme historically used for RTTY, answer C. It isn't a 7-bit scheme with parity, doesn't include built-in error detection/correction, and SELCAL/LISTEN describe an unrelated selective-calling system, so A, B, and D are wrong.
