Hey guys, I've searched and searched but I can't seem to find any help on this question I have.
Express the following bit pattern 10011001 in:
a) Unsigned integer
b) Signed integer in sign-magnitude notation
c) Signed integer in Twos-compliment
I don't understand what these means and I've looked online but I can only find converters etc but I need to learn how do do this with pen and pad for my exams. Please try to explain the best you can if you can. Thanks.
