Across

1. An operator that returns true if at least one operand is true.

2. Circuit that adds two binary digits and outputs the sum and carry

3. Logic gate that outputs true only when all of its inputs are false

4. An operator that returns the opposite of a logical value.

5. An operator that returns true if exactly one operand is true.

6. Logic gate that outputs true unless all of its inputs are true

Down

7. Logic gate that outputs true when the number of true inputs is even

8. Logic gate that outputs true when the number of true inputs is odd

9. Logic gate that outputs true only when all of its inputs are true

10. Basic components of digital circuits that perform logical operations

11. An operator that returns true if both operands are true.

12. Logic gate that inverts the input signal

13. Circuit that adds three binary digits and outputs the sum and carry
