📝 Error Detection in Block Coding

Q1. Given dataword \(01\) is encoded as codeword \(011\), if a single‑bit error flips the second bit, which of the following codewords would the receiver detect as erroneous?

💡 Difficulty: easy | ✅ Correct: B

Q2. If a transmitted codeword \(011\) suffers a burst error affecting the last two bits, which of the following received words could still pass the parity check?

💡 Difficulty: medium | ✅ Correct: D

Q3. When a code with minimum Hamming distance \(d_{\min}=3\) is used, what is the maximum number of detectable errors?

💡 Difficulty: hard | ✅ Correct: B
