A small example

Binary of 1011 -
1101

Steps
1. write the msb as itseif (here retain fourth bit say 1 ) and it will be the
msb of binary.
2. add the msb of binary (say 1) with next bit of gray (say 0 ie third bit )and
the sum (1) becomes next bit of binary. note: if any carry generated just discard
it.
3. previous sum (1) is again added with next bit of gray(1 ie second bit) and
this sum(0) becomes second bit of binary .
4. previous sum (0) is again added with next bit of gray (1 ie first bit) and
the sum (1) becomes first bit of binary.
