1. What is the boolean expression for this NOT gate?

Y = A

Y = NOT A

NOT Y = Y

A = Y

2. What is the boolean expression for this AND gate?

A AND B

Y AND A

Y = A AND B

Y = A OR B

3. What is the boolean expression for this OR gate?

Y = A AND B

NOT Y = AB

Y = A OR B

A OR B = A

4. Write the boolean expression for this circuit - -

O = A AND B NOT

O = NOT (A AND B)

None of the above

O = (A OR B) NOT

5. Write the boolean expression for this circuit - - -

O = A NOT B NOT B

None of the above

O = NOT (A OR B)

O = NOT A AND NOT B

6. Write the boolean expression for this circuit -

O = (NOT A) AND B

O = NOT B AND NOT A

None of the above

O = NOT A OR NOT AND B

It has one output S

It has for inputs, A, B, S and C

It has two outputs S and C

It has three inputs A, B, C

8. What is the boolean expression for S?

S = A AND B NOT E

S = (A OR B) AND (NOT E) AND C

S = A OR B NOT B

None of the answers here are correct

9. What would the boolean expression be for the output C?

C = A AND C

C = S AND B

A = A AND B

C = A AND B

10. Write the boolean expression for this particular logic diagram (note that you can use brackets to denote an 'AND' as this is essentially like multiplication)
```Don't forget that a + is an OR gate and a .
(or brackets) is an AND gate. ```

C(D) + A

A(BD) + C

(AB + C)D

A + C (D)
