What is a logic gate?
A logic gate is an electronic component that processes one or more input signals to produce a single output signal based on a certain logic function.
True or False: An AND gate produces a true output only when all its inputs are true.
True
Fill in the blank: A _____ gate outputs true if at least one of its inputs is true.
OR
What is the symbol for a NOT gate?
The symbol for a NOT gate is a triangle pointing to the right with a small circle (representing inversion) at the output.
Which logic gate is also known as a universal gate?
NAND gate
What are the two main types of logic gates?
Combinational logic gates and sequential logic gates.
Multiple Choice: What is the output of an XOR gate if both inputs are true? A) True B) False
B) False
True or False: A NOR gate is a combination of an OR gate followed by a NOT gate.
True
What is the output of an AND gate if one input is false?
The output will be false.
Fill in the blank: The output of a NAND gate is the _____ of the AND gate.
inverse
What logic gate can be used to create any other type of logic gate?
NAND gate
Multiple Choice: Which of the following represents an OR gate? A) + B) * C) ~
A) +
What is the primary function of a buffer in digital circuits?
To strengthen a signal without changing its value.
True or False: The output of an XNOR gate is true when both inputs are different.
False
What is the role of a multiplexer in relation to logic gates?
A multiplexer selects one of many input signals and forwards the selected input into a single line.
