Hamming (7,4) Encoder

The output word uses standard Hamming positions: o_code(0)=p1, o_code(1)=p2, o_code(2)=d0, o_code(3)=p4, o_code(4)=d1, o_code(5)=d2, o_code(6)=d3. Parity is even.

Behaviour

• p1 covers positions 1, 3, 5 and 7;
• p2 covers positions 2, 3, 6 and 7;
• p4 covers positions 4, 5, 6 and 7;
• the circuit is combinational.
