Logic Gate Formulas/Expressions

What is the boolean expression for this logic circuit?

• Q = NOT (A OR B)

• Q = NOT A AND B

• NOT A OR B = Q

• Q = (NOT A) OR B

Answer explanation

The logic circuit is represented by the boolean expression 'Q = (NOT A) OR B'. This indicates that Q is true if A is not true or if B is true. Other options either do not follow the correct logic or incorrectly represent the negation.

Which logic gate outputs 1 only when both inputs are 1?

• AND

• OR

• NOT

• XOR

25!=14

• True

• False

10 < 6 || 26 != 14

• True

• False

6 < 7 && 6 > 7

• True

• False

5 < 7 AND 6 > 7

• True

• False

(Not True) OR ( (5 < 4) || (Not True) )

• True

• False
