This makes it useful in many applications where it is important to detect small changes in a signal, such as in digital communications and computer memory.<\/p>\n<p>The Gray code for decimal 7 is 1011. This can be seen by considering the binary representation of 7, which is 111. If we start with 111 and change only one bit, we get 1011.
