1. Determine the decimal value of each of the following unsigned binary numbers:
a. 10011001=153



b. 01110100=116



c. 10111111=191



2. Determine the decimal value of each of the following signed binary numbers displayed in
the 2’s complement form:
a. 10011001= -103


b. 01110100= 116


c. 10111111= -65

3. Determine the outputs (Cout, Sout) of a full-adder for each of the following inputs:
a. A = 1, B = 0, Cin = 0 Sout=1 Cout=0


b. A = 0, B = 1, Cin = 1 Sout=0 Cout=1


c. A = 0, B = 0, Cin = 1 Sout=1 Cout=0


d. A = 1, B = 1, Cin = 1 Sout=1 Cout=1

, 4. The circuit below is an attempt to build a half-adder. Will the Cout and Sout function
properly? Demonstrate your rationale.

No it will not work as a half adder circuit. If you go through the truth table for the circuit
it will not match. For example both inputs at 0 should give you Cout/Sout as 0 because
you are
