The given code is the excess-3 code.

In gray code any two successive numbers will be differed by only one bit position. but it is not true that the gray code number is 3 greater than binary equalent of that number.

For example the gray code of a binary number 1000 is 1100(difference is 4)
similarly for 1111 is 1000 (difference is 7).

What is meant by grey code?

Grey code is number which is obtained by giving one bit variation starting from least significant bit.

Please explain grey code in a simple way.

Karnaugh map is a good example of grey code. When we move from one block to another only one bit/number must change. The 1st block we have (00), second block we have (01), third block we have (11). See that, when we move from one block to another only one bit/ number changes.
