What is the gray code for 1111?

To convert the binary number 1111 to Gray code, you keep the most significant bit (MSB) the same and then perform an XOR operation between each bit and the bit to its left. The conversion steps are as follows: the MSB is 1, the second bit is 1 XOR 1 = 0, the third bit is 1 XOR 1 = 0, and the fourth bit is 1 XOR 1 = 0. Therefore, the Gray code for 1111 is 1000.
