4.5.4.1 Unsigned binary and 4.5.4.3 Signed binary using two’s complement

Question 1

What is the difference between unsigned binary and

signed binary

Answer 1

unsigned binary - fixed-point system
signed binary - the value holds a positive or negative value using it’s most significant bit (the last bit to the left), the “signed bit”

Question 2

What is the minimum value in unsigned binary?

Answer 2

0

Question 3

What is the maximum value in unsigned binary?

Answer 3

2^(n) -1

n = number of bits

Question 4

What is the range of values in two’s complement binary?

Answer 4

• ( 2^(n-1)) to 2^(n-1) - 1

e. g in 8 bits, range is -128 to 127

Question 5

What is the number of possible values in unsigned binary?

Answer 5

2^n

n = number of bits
