1.0    Two bit binary adder

1.1    Design a two bit binary adder from logic gates. You can have the circuit by cascading a half adder with a full adder since you do not need CIN for the first bit addition. (Hint: You do not need the carry in, CIN input signal for the first bit addition. You will only need the CIN signal for the second bit.)

1.2    Give the types, number and quantity of chips that will be used to build the circuit in the lab.
 

2.0    Arithmetic Addition in Binary

2.1    Perform the following binary arithmetic additions in the log book:
        ( i )    0000 + 0000 =
       ( ii )    1111 + 1111 =
      ( iii )    1010 + 0101 =
      ( iv )    0101 + 1010 =
       ( v )    1100 + 1111 =
 

3.0    Arithmetic Subtraction in Binary

3.1    Perform the following binary subtraction in the log book:
        ( i )    1111 - 0000 =
       ( ii )    0110 - 0100 =
      ( iii )    0000 - 0100 =
      ( iv )    0100 - 0110 =
