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?

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?

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 $q=2$

For any natural number $n$, an ordering of all binary strings of length $n$ is a Gray code if it starts with $0^n$, and any successive strings in the ordering differ in exactly one bit (the first and last string must also differ by one bit). Thus, for $n=3$ ... Gray code, if two strings are separated by $k$ other strings in the ordering, then they must differ in exactly $k$ bits none of the above

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) $
