Detailed Solution for Test: Logic Expressions - Question 6

(A XOR B) OR (C AND D) translates to (A OR B) OR (C AND D).

Test: Logic Expressions - Question 7

Which logic gate outputs a high signal if and only if its inputs are different?

Detailed Solution for Test: Logic Expressions - Question 7

The XOR gate outputs a high signal when its inputs are different.

Test: Logic Expressions - Question 8

Express the logic circuit (NOT A) AND (B OR C) using a logic expression.

Detailed Solution for Test: Logic Expressions - Question 8

(NOT A) AND (B OR C) represents the given logic circuit.

Test: Logic Expressions - Question 9

What is the logic expression for the NOR gate?

Detailed Solution for Test: Logic Expressions - Question 9

The NOR gate outputs the complement of the AND operation between A and B.

Test: Logic Expressions - Question 10

Express the logic circuit (A AND B) OR (NOT B) using a logic expression.

Detailed Solution for Test: Logic Expressions - Question 10

(A AND B) OR (NOT B) is already expressed as a logic circuit.
