An embedded computer uses $8$-bit $2$'s complement representation for signed integers. What is the minimum negative integer value which can be represented in this computer?
🎥 Video solution / Text Solution of this question is given below:
In $n$-bit $2$'s complement representation, the range of signed integers is:
$-2^{n-1}$ to $2^{n-1}-1$
Here,
$n=8$
So, range is:
$-2^{7}$ to $2^{7}-1$
$=-128$ to $127$
Therefore, the minimum negative integer value is $-128$.
