Sorry? I dont know how to do it like that . I just know how to do likeWork out a truth table for 0-16 and then invert it.
Where is the value zero in that range with only the inversion?
The answer is yes.Hello,
Im trying to do -4 as a four bit 2's complement notation
So far I have
8 4 2 1
0 1 0 0
1 0 1 1 <-- flip over
<-- Do I have to add +1 to the ones in flip over Im not sure ! Im lost can somebody help me out thanks!
OK IM really lost am I right or what? why somebody else is telling me about something that I never hear with my teacher about truth table and now you are telling me my answer is yes which answeR?? IM LOST!The answer is yes.
To check your answer, count how many ones you need to add to get to zero.
Not as long as you are using a 4-bit number. There's no difference in a 4-bit unsigned number versus a 4-bit signed number, except in ways of interpretation.think you still need a sign bit. The value of -4 is 1100, but I'm thinking you need a 1 at the beginning to show that it's negative 4 instead of 12?
1 1100?
Sorry, it's been a while for me
