UGC NET CSE | December 2010 | Part 2 | Question: 10

Question

Encoding of data bits $0011$ into $7$-bit even Parity Hamming Code is

• A. $0011110$ 
• B. $0101110$
• C. $0010110$
• D. $0011100$

Answer 1

Option A

bit pattern is D7 D6 D5 P4 D3 P2 P1 

P1 (check even parity at 1,3,5,7 bit) = 0

P2 (check even parity at 2,3,6,7 bit) = 1

P4 (check even parity at 4,5,6,7 bit) = 1

so final code is 0011110.
