Question 13 of 67
Convert the following logic gate circuit into a Boolean expression, writing Boolean sub-expressions next to each gate output in the diagram:
Reveal answer
Notes:The process of converting gate circuits into Boolean expressions is really quite simple, if you proceed gate by gate. Have your students share whatever methods or “tricks” they use to write the expressions with the rest of the class.

Convert the following relay logic circuit into a Boolean expression, writing Boolean sub-expressions next to each relay coil and lamp in the diagram:
Reveal answer
Notes:The process of converting relay logic circuits into Boolean expressions is not quite as simple as it is converting gate circuits into Boolean expressions, but it is manageable. Have your students share whatever methods or “tricks” they use to write the expressions with the rest of the class.
Question 29, answer 3 has a typo - should be A*B + !(D)*E not A*B+!(D*E)
