Digital Logic - Gray Code Representation
Hi, Can someone please tell if gray code representation can also work for negative binary number? I’ve seen examples of gray code for only positive binary number not sure about negative , can someone pls clear the doubt ?

Decimal to Binary and Hex -- 300 in 8-bit binary gives me a 9-bit number?
So I'm asked to convert 300 (decimal) into binary and hexadecimal for a single byte (8-bit) unsigned number. I get: 300 = 100101100 = 12C But isn't 100101100 a 9 digit number, and so a 9-bit number? Am I missing something here?

Excess 3
In Excess 3 addition, the groups that have produced a carry we have to add 0011 to them and subtract 0011 from the groups which have not produced a carry during the addition. Can someone explain the logic of performing this step for me?

GATE CSE 2017 Set 2 | Question: 34
Consider the binary code that consists of only four valid codewords as given below: $00000, 01011, 10101, 11110$ Let the minimum Hamming distance of the code $p$ and the maximum number of erroneous bits that can be corrected by the code be $q$. Then the values of $p$ and $q$ are $p=3$ and $q=1$ $p=3$ and $q=2$ $p=4$ and $q=1$ $p=4$ and $q=2$

GATE CSE 2006 | Question: 40
Consider numbers represented in 4-bit Gray code. Let $ h_{3}h_{2}h_{1}h_{0}$ be the Gray code representation of a number $n$ and let $ g_{3}g_{2}g_{1}g_{0}$ be the Gray code of $ (n+1)(modulo 16)$ ... $ g_{3}(h_{3}h_{2}h_{1}h_{0})=\sum (0,1,6,7,10,11,12,13) $
