Logic gates - Flashcards

Question	Answer
Name the four main types of logic gate.	AND OR XOR NOT
Sketch a NOT gate.	Placeholder
Draw the truth table for a NOT gate.	Placeholder
Describe what a NOT gate does.	A NOT gate takes in one input, reverses it and then outputs it.
Which logic gate has only one input?	A NOT gate only has one input.
Sketch an AND gate.	Placeholder.
Draw the truth table for an AND gate.	Placeholder.
Describe what an AND gate does.	An AND gate takes in two inputs. If BOTH inputs are true, then the output is true. Otherwise the output is false.
Sketch an OR gate.	Placeholder.
Draw the truth table for an OR gate.	Placeholder.
Describe what an OR gate does.	An OR gate takes two inputs. If neither input is true, then the output is false. Otherwise, the output is true.
Sketch a XOR gate.	Placeholder
Draw the truth table for a XOR gate.	placeholder
Describe what a XOR gate does.	A XOR gate takes to inputs. If ONLY ONE input is true, then the output is true. Otherwise, the output is false.
Which logic gate is this?	AND gate
Which logic gate is this?	OR gate
Which logic gate is this?	XOR gate
Which logic gate is this?	NOT gate
Look at the following logic circuit. If a, b and c are all true, what is the output?	The output is false.
