EEE 120 Final Questions and Correct
Answers/ Latest Update / Already Graded
What are you NOT allowed to do when building digital logic circuits?
(Multiple correct answers are possible. Wrong answers will deduct
points.)
Ans: 1. Connect multiple outputs of different gates.
2. Connect an output of a logic gate to twelve inputs of
different gates.
Which gate generates a true output only if an odd number of inputs is
true?
Ans: XOR
Which of the following statement(s) are true? (Multiple correct answers
are possible. Wrong answers will deduct points.)
Ans: 1. A circuit with 4 inputs has 16 possible combinations
(truth table lines).
2. All circuits can be created using only NOR gates.
3. You should never tie 2 outputs of two distinct circuits
together.
Which 3-input gate outputs a false value only when all inputs are true?

Ans: NAND
Can you construct an XOR gate using only AND/OR/NOT gate(s)?
Ans: True
Which of the following statements are true?
Ans: 1. K-Map and Boolean Algebra can be used to simplify
circuits.
2. Equations can be derived from K-Maps using SOP and POS.
Which gate on the list is considered "functionally complete", which
means that you can construct a NOT gate, an AND gate and an OR
gate using a combination of only this particular gate?
Ans: NAND
Which is the minimum SOP expression for the function F(X,Y,Z) = (X +
Y')' Z + (XZ)' + Y ? No partial credit is granted for incomplete
simplifications.
Ans: X' + Y + Z'
