📝 Redundancy error detecting and correcting

Q1. If a burst error flips 3 consecutive bits in a byte, which of the following statements best describes the likely impact on a simple even parity check?

💡 Difficulty: easy | ✅ Correct: B

Q2. A communication link uses a 2‑bit checksum for error detection. If a burst error affecting 4 bits occurs, what can be inferred about the probability that the error goes undetected compared to a single‑bit error?

💡 Difficulty: medium | ✅ Correct: A

Q3. Differentiate the detection capability of a CRC with a degree‑3 polynomial versus a degree‑4 polynomial for burst errors up to length 3. Which statement is correct?

💡 Difficulty: hard | ✅ Correct: C
