Hamming Code Circuit

Given the following Hamming Code, I was tasked to implement the following circuits using gates.

• Transmiter Circuit (Parity Bit Generator).



• Error Detector Circuit of the receptor (Parity Check).


• Data Bit Corrector.

I did the first two circuits, but I can't seem to figure out the corrector circuit.

Parity Bit Generator Circuit:

Parity Check Circuit:

I was hoping for a little push to help me finish the rest of the circuit.

Thanks in advance.
