EEE 120 FINAL EXAM ACTUAL
EXAMINATION 2026 QUESTIONS WITH
ANSWERS GRADED A+
⫸ Which gate generates a true output only if an odd number of inputs is
true? Answer: XOR
⫸ Which of the following statement(s) are true? (Multiple correct
answers are possible. Wrong answers will deduct points.) Answer: 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? Answer: NAND
⫸ Can you construct an XOR gate using only AND/OR/NOT gate(s)?
Answer: True
⫸ Which of the following statements are true? Answer: 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? Answer: 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. Answer: X' + Y + Z'
⫸ Convert the following unsigned binary number to decimal number:
1010 1010 Answer: 170
⫸ How many binary digits (bits) does a Byte have? Answer: 8
⫸ Which is the correct hexadecimal number corresponding to the binary
number 1010 1011? Answer: AB
⫸ Convert the following decimal number to hexadecimal: 88 Answer:
58
⫸ Which is the correct 8-bit binary number corresponding to the
decimal number 88? Answer: 01011000
⫸ What is the decimal number -54 in signed binary. Answer: 1001010
⫸ Somebody was asked to perform an addition of the two 6-bit signed
integers 100111 + 110111 by calculating the decimal equivalent of each
