📝 Sample Questions

Q1. If a transmitted codeword is divided by the generator polynomial \(g(x)=x^3+x+1\) and the remainder is non‑zero, what can be inferred about the received word?

🔹 A. No errors
🔹 B. Single‑bit error
🔹 C. Multiple‑bit error
🔹 D. Undetectable error

💡 Difficulty: easy | ✅ Correct: C

Q2. Two cyclic encoders use generator polynomials \(g_a(x)=x^3+x^2+1\) and \(g_b(x)=x^3+x+1\). For the same 5‑bit message, which encoder tends to produce codewords with higher average Hamming weight?

🔹 A. Encoder A
🔹 B. Encoder B
🔹 C. Both equal
🔹 D. Depends on the specific message

💡 Difficulty: medium | ✅ Correct: A

Q3. Compare the error‑detecting capability of generator polynomials \(g_1(x)=x^4+x+1\) and \(g_2(x)=x^4+x^3+1\) for a 7‑bit message. Which statement is true?

🔹 A. Both detect any single‑bit error
🔹 B. \(g_1\) detects all double‑bit errors
🔹 C. \(g_2\) cannot detect odd‑weight errors
🔹 D. \(g_1\) has a larger Hamming distance

💡 Difficulty: easy | ✅ Correct: A
