Q1. What is the purpose of a 1‑bit shift register in the CRC encoder?

🔹 A. Store the data permanently
🔹 B. Hold a bit for one clock cycle
🔹 C. Perform XOR operations
🔹 D. Generate the system clock

💡 Difficulty: easy | ✅ Correct: B

Q2. Compare the hardware resource usage when the encoder uses n shift registers versus n−k shift registers. Which statement is correct?

🔹 A. Using n shift registers consumes more resources than using n−k
🔹 B. Using n−k shift registers consumes more resources than using n
🔹 C. Both configurations use the same number of registers
🔹 D. The required number depends on the generator polynomial

💡 Difficulty: medium | ✅ Correct: B

Q3. Assume a CRC encoder uses n=16, k=12. If a single‑bit error occurs at position 5 of the transmitted codeword, what is the probability that the error will be detected, assuming the generator polynomial is primitive?

🔹 A. 1
🔹 B. 0.5
🔹 C. 0.75
🔹 D. 0.25

💡 Difficulty: hard | ✅ Correct: A
