    I am having trouble with a gray code 4-bit adder. I figured out how to design a 3 bit with no trouble. I got the state table, am having trouble with the k-maps and the logic diagram. Please assist me in solving his problem. Below is the sequence for 4 bit grey code.

    0000 0001 0011 0010 0110 0111 0101 0100 1100 1101 1111 1110 1010 1011 1001 1000.

    Thanks in Advance.

    It may be an idea to upload the state-table and your workings for the 3-bit for us to have a look at.

    Attached is the state table. Also I need to implement this using D flip-flips, where as the 3-bit I could use JK flip-Flops. Thanks.
