3 cards from this section. Quick, good the night before a test.
What is the output of an AND gate when both inputs are true?
Think about what AND means.
What does a NOT gate do?
Remember it switches true to false.
What does an AND gate output if A=1 and B=0?
Remember, AND is demanding.
A NOR gate outputs true when:
Think about what OR means when negated.
Build a truth table for a circuit with two inputs A and B which goes through both an AND and then a NOT gate.
Try filling out the truth table step by step.
Design a digital circuit that uses NAND gates only to create an OR gate.
Think about how NAND can be rearranged to give positive inputs.
