Q1. Conver the following grey code to binary
Ans. 
Grey code is a binary numeral system where two successive values differ in only one bit.
• To convert Grey code to binary, start with the most significant bit and XOR each bit with the previous bit.

• For example, to convert Grey code 1010 to binary: 1 XOR 0 = 1, 0 XOR 1 = 1, 1 XOR 1 = 0, 0 XOR 1 = 1. So, the binary equivalent is 1101.
