How many parity bits are required for a standard Hamming code with 4 data bits?
Options
A.
1
B.
2
C.
3
D.
4
E.
None of the above
Correct Answer (Detailed Explanation is Below)
C.
3
Detailed Explanation
Correct Answer: (C) 3 For m data bits and r parity bits, the condition is 2ʳ ≥ m + r + 1. For m = 4: r = 3 gives 2³ = 8 and 4 + 3 + 1 = 8. Therefore, 3 parity bits are required.
