07 - Statement to Diagram Practice

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

  Y = A

  NOT Y = Y

  A = Y

  Y = NOT A

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

  Y AND A

  Y = A AND B

  A AND B

  Y = A OR B

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

  NOT Y = AB

  Y = A OR B

  A OR B = A

  Y = A AND B

 4. Write the boolean expression for this circuit - -

  None of the above

  O = NOT (A AND B)

  O = A AND B NOT

  O = (A OR B) NOT

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

  O = NOT A AND NOT B

  O = A NOT B NOT B

  O = NOT (A OR B)

  None of the above

 6. Write the boolean expression for this circuit -
booleanstatement_output3.png

  O = NOT B AND NOT A

  None of the above

  O = (NOT A) AND B

  O = NOT A OR NOT AND B

 7. What do you notice about this logic diagram?
booleanstatement_twooutputs.png

  It has one output S

  It has two outputs S and C

  It has for inputs, A, B, S and C

  It has three inputs A, B, C

 8. What is the boolean expression for S?
booleanstatement_twooutputs.png

  S = A OR B NOT B

  S = A AND B NOT E

  None of the answers here are correct

  S = (A OR B) AND (NOT E) AND C

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

  C = A AND C

  C = S AND B

  C = A AND B

  A = A AND B

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

  A(BD) + C

  (AB + C)D

  A + C (D)

  C(D) + A
