Deep Dive: G8C04
The correct answer is C: A 5-bit code with additional start and stop bits. What describes Baudot code is a 5-bit code with additional start and stop bits. Baudot code uses 5 data bits plus start and stop bits for character encoding. For amateur radio operators, this is the code used in RTTY. Understanding this helps when operating RTTY.
Why Other Answers Are Wrong
Option A: Incorrect. 7-bit code with start, stop, and parity bits is ASCII, not Baudot - Baudot is 5-bit. 7-bit is ASCII. Option B: Incorrect. Code using error detection and correction describes modern codes, not Baudot - Baudot is simple 5-bit code. Error correction isn't Baudot. Option D: Incorrect. Code using SELCAL and LISTEN describes selective calling, not Baudot code - Baudot is 5-bit character code. SELCAL/LISTEN are different.
Exam Tip
Baudot code = 5-bit code with start and stop bits. Think 'B'audot = 'B'asic '5'-bit code. Baudot code uses 5 data bits plus start and stop bits for character encoding. Not 7-bit (ASCII), not error correction, not SELCAL - just 5-bit with start/stop.
Memory Aid
Baudot code = 5-bit code with start and stop bits. Think 'B'audot = 'B'asic '5'-bit. Baudot code uses 5 data bits plus start and stop bits. Standard RTTY character code.
Real-World Example
Baudot code: Each character is encoded using 5 data bits, plus a start bit and stop bit(s). This creates a 7-8 bit frame per character. Baudot code is used in RTTY (Radio Teletype) - it's the standard 5-bit code for amateur RTTY. This is how Baudot code works.
