| Q. |
A full adder logic circuit will have |
| A. | two inputs and one output |
| B. | three inputs and three outputs |
| C. | two inputs and two outputs |
| D. | three inputs and two outputs |
| Answer» D. three inputs and two outputs | |
| Explanation: a full adder circuit will add two bits and it will also accounts the carry input generated in the previous stage. thus three inputs and two outputs (sum and carry) are there. in case of half adder circuit, there are only two inputs bits and two outputs (sum and carry). | |
