For one single-bit error correction, use the odd-parity Venn diagram below. Regions for 4 bits are AB, ABC, AC, and BC (Region AB holds the most significant bit and Region BC holds the least significant bit). The check bits are in A, B, and C. Determine if the 7-bit Codeword and the 4-bit memory Word are correct. What is the correct 4-bit Word?
