Neco 2019 Data Processing Question 9
Practice objective / multiple choice question 9 from the 2019 Neco Data Processing examination.
A 7‑bit Hamming (7,4) code is used with even parity. The original 4 data bits are \(d_1d_2d_3d_4 = 1011\). Parity bits are placed at positions 1, 2 and 4. The transmitted code is therefore \(0110011\). During transmission, bit position 5 is flipped. The received code is \(0110111\). Using syndrome decoding, identify the erroneous bit, correct the code, and state the original 4 data bits.
