Binary to Gray code conversion

The Binary to Gray code converter is a logical circuit that is used to convert the binary code into its equivalent Gray code. By putting the MSB of 1 below the axis and the MSB of 1 above the axis and reflecting the (n-1) bit code about an axis after 2^n-1 rows, we can obtain the n-bit gray code.

In 4-bit gray code, the 3-bit code is reflected against the axis drawn after the 2^4-1-1^th =8^th row.

Just like Binary to Gray code conversion; it is also a very simple process. There are the following steps used to convert the Gray code into binary.

• Just like binary to gray, in gray to binary, the 1^st bit of the binary number is similar to the MSB of the Gray code.
• The 2^nd bit of the binary number is the same as the 1^st bit of the binary number when the 2^nd bit of the Gray code is 0; otherwise, the 2^nd bit is altered bit of the 1^st bit of binary number. It means if the 1^st bit of the binary is 1, then the 2^nd bit is 0, and if it is 0, then the 2^nd bit be 1.
• The 2^nd step continues for all the bits of the binary number.
