🔍 Key Concepts

• SITOR (Simplex Teletype Over Radio) character structure • Difference between Baudot code and error‑detecting / error‑correcting codes • How many bits are used in typical ARQ (Automatic Repeat reQuest) systems for redundancy

💭 Think About

• First, recall what kind of service SITOR-A and SITOR-B provide and why error detection is important there. • Think about whether SITOR uses an older teleprinter code directly, or whether it modifies the characters to help the receiver detect errors. • Compare the answer choices: which ones describe a fixed pattern of zeros and ones per character, and which one just describes raw data bits plus extra bits?

✅ Before You Answer

• Check whether SITOR characters are designed so every character has the same number of “ones” and “zeros”. • Verify if SITOR uses a constant-weight, 7-bit code derived from but not identical to standard Baudot. • Confirm whether SITOR’s error detection is achieved by the pattern of bits in each character rather than by adding extra separate parity bits.
