Logic Gates and Boolean Expressions Quiz

What is the output of a NOT gate when the input is 0?

• Undefined

• 1

• 0

• Same as input

Which gate outputs true only if both inputs are true?

• OR

• AND

• NOT

• XOR

How can you remember the shape of an OR gate?

• It resembles a T

• It looks like a D

• It fits around the letter O

• It has a line crossing through it

What is the first step in constructing a truth table for a logic diagram?

• Identify the final output

• List all possible input combinations

• Draw the logic diagram

• Write the Boolean expression

In a truth table, what does the column for interim outputs represent?

• The initial inputs

• The final result

• Temporary results between gates

What is a universal logic gate?

• A gate that cannot be combined with others

• A gate that is used in all circuits

• A gate that only outputs true
