So I am converting from Grey to binary as inputs ABCD and outputs wxyz. I have a solution that doesn't match up to the K-map I created from the truth table of Grey to Binary.

My K-map ends up for x becoming just A and for my y value becomes just C when that doesn't really match up and is incorrect when converting the values.

The order of the map is for rows A to B and for columns C to D.

The method I used to place minterms on the k-map were look for where 1s are within the x term within the binary portion of the truth table for the x k-map and place a 1 within that respective index slot.

The ordering of the minterm box numbers are 0 1 3 2 for the first row, 4 5 7 6 for the second, 12 13 15 14 third, and 8 9 10 11 for the last row.

 

Never mind, I had to manually check the number to when the function would equal 1 and see the square space it went into. I don't know why when the grid was arranged the way it was it wouldn't just fall into place within the minterm box designation properly.
