    Logic.
  2. With regard to computer logic circuits, what is meant by "complement?"
    The opposite of the original statement.
  3. What are the complements of the following terms? (a.) Q (b.) R (c.) V (d.) Z
    • (a.) Q (not _ placed above)
    • (b.) R (not _ placed above)
    • (c.) V (not _ placed above)
    • (d.) Z (not _ place above)
  4. If logic 1 = -5 vdc and logic 0 = -10 vdc, what logic polarity is being used?
    Positive.
  5. If logic 1 = +2 vdc and logic 0 = -2 vdc, what logic polarity is being used?
    Positive.
  6. If logic 1 = -5 vdc and logic 0 = 0 vdc, what logic polarity is being used?
    Negative.
  7. What is the Boolean expression for the output of an AND gate that has R and S as inputs?
    f = R x S.
  8. What must be the logic state of R and S to produce the TRUE output on an AND gate?
    Both must be 1s (HIGH) at the same time.
  9. How many input combinations exist for a four-input AND gate?
    16.
  10. Write the Boolean expression for an OR gate having G, K, and L as inputs.
    f = G+K+L.
  11. How many input combinations are possible using G, K, and L to an OR gate?
    Eight.
  12. Using inputs G, K, and L to an OR gate. How many of those combinations will produce a HIGH output?
    Seven.
  13. What is the complement of XYZ?
    XYZ (not _ placed above)
  14. In a properly functioning circuit, can both the input and output of an inverter be HIGH at the same time?
    No.
  15. A NAND gate has Z and X as inputs. What will be the output logic level if Z is HIGH and X is LOW?
    HIGH.
  16. What must be the state of the inputs to a NAND gate in order to produce a LOW output?
    All inputs must be HIGH.
  17. A NAND gate has inputs labeled as A, B(not), and C. If A and B(not) are HIGH, C must be at what logic level to produce a HIGH output?
    Low.
  18. How does a NOR gate differ from an OR gate?
    It has an inverter on the output.
  19. What will be the output of a NOR gate when both inputs are HIGH?
    Low.
  20. In what state must the inputs to a NOR gate be in order to produce a logic 1 output?
    All inputs must be low.
  21. What is the output Boolean expression for an AND gate with A and B as inputs when the B input is inverted?
    A B(not)
  22. What is the equivalent logic gate of a two-input NAND gate with both inputs inverted?
    OR gate.
  23. Boolean algebra is based on the assumption that most quantities have _______ conditions.
    Two.
  24. Boolean algebra is used primarily by _______ to simplify circuits.
    Design engineers.
