Building an Adder The Boolean operations can be built electronically using transistors. Applying an electrical current to a terminal is the equivalent to 1 or True. No current means 0 or False. Using a combination of these operations wired together, we can do simple arithmetic. Further combinations and the use of electronic storage enable use to do more complex calculations.
Adder A AND D B XOR E This adds the inputs A and B. The output is shown by D and E together.
Input Output + + + +
D A AND XOR G B AND F XOR E XOR H C This adds the inputs A, B and C. The output is shown by G and H together.
Input Output + + + + + + + + + + + + + + + +
