Why is gray code called reflected code?
<p>I understand that each gray code differs from its preceding code by one bit, but i don't exactly understand why its called reflected. I came across this website <a href="https://www.pc-control.co.uk/gray_code.htm" rel="noreferrer">https://www.pc-control.co.uk/gray_code.htm</a>, where it says " The gray code is sometimes referred to as reflected binary, because the first eight values compare with those of the last 8 values, but in reverse order", but the first 8 gray codes are not comparable to the last 8 gray codes in reverse order as can be seen from the gray code table on their website. To add to my confusion the gray code table differs from the gray code table on my textbook, for eg gray code for 9 = 1000 on my textbook while on the website its 9 = 1101.</p>
