Which logic gate gives an output of 1 only when both inputs are 1?
OR
AND
NOT
XOR
Which symbol is typically used to represent an OR gate in a circuit diagram?
A D-shaped symbol with a straight back
A triangle with a small circle at the tip
A curved input and pointed output shape
A rectangle with a single input
The NOT gate is also known as:
Inverter
Pass-through
Stopper
Reflector
What is the output of a NOT gate when the input is 1?
1
0
Depends on other inputs
No output
The OR gate outputs 1 when:
Both inputs are 1
At least one input is 1
All inputs are 0
Only when inputs are different
Which gate produces an output of 0 only when both inputs are 1?
OR
NAND
XOR
AND
What is the output of a NOR gate when both inputs are 0?
0
1
Depends on previous input
Can’t be determined
The XOR gate outputs 1 when:
Inputs are the same
Inputs are both 0
Inputs are different
All inputs are 1
Which logic gate is a combination of an OR gate followed by a NOT gate?
NOR
NAND
XOR
XNOR
The XNOR gate gives an output of 1 when:
Both inputs are 1
Inputs are different
Inputs are the same
Only one input is 1
Which of the following gates is known as the “unlike detector” because it outputs 1 when inputs are different?
AND
XNOR
XOR
NOR
Which Boolean expression represents an AND gate with inputs A and B?
