Logic gates Flashcards
(11 cards)
What is the purpose of logic gates?
Logic gates are digital process devices that respond to and emit signals that are either high or low.
What do high signals represent in logic gates?
High signals are represented by logic 1.
What do low signals represent in logic gates?
Low signals are represented by logic 0.
What are truth tables used for?
Truth tables are used to show the output signals each type of logic gate produces for given input signals.
What is the output of an AND gate when both inputs are high?
High (1)
What is the output of an AND gate when either or both inputs are low?
Low (0)
Complete the statement: An OR gate produces a high output signal when _______.
either or both input signals are high (1)
What is the output of an OR gate when both inputs are low?
Low (0)
What is the output of a NOT gate when the input signal is low?
High (1)
What is the output of a NOT gate when the input signal is high?
Low (0)
List the three types of basic logic gates.
- AND gates
- OR gates
- NOT gates
