Logic Gate

What is this logic gate called?

• OR gate

• AND gate

• XOR gate

• NOT gate

Answer explanation

The logic gate shown is called an AND gate because it performs the logical AND operation on its inputs.

What is this logic gate called?

• XOR gate

• NOT gate

• OR gate

• AND gate

Answer explanation

The logic gate shown is an OR gate, which outputs true when at least one input is true. It is used to combine multiple signals in digital circuits.

What is the name of this logic gate?

• OR gate

• NOT gate

• XOR gate

• AND gate

Answer explanation

A NOT logical operator will produce an output which is the opposite of the input. The symbol for NOT is ¬

What is the output of this logic diagram?

• 0

• 1

Answer explanation

An AND logical operator will output 1 only if both inputs are also 1.

​

The symbol for AND is ∧

What is the output of this logic diagram?

• 0

• 1

Answer explanation

An OR logical operator will output 1 if either input is 1.

​The symbol for OR is ∨

What is the output of this logic diagram?

• 0

• 1

Answer explanation

A NOT logical operator will produce an output which is the opposite of the input.

Which is the truth table for the AND gate?

• 
• 
• 

Answer explanation

An AND logical operator will output 1 only if both inputs are also 1.

This is the truth table for which logic gate?

• AND

• OR

• NOT

Answer explanation

The truth table provided matches the logic gate OR, where the output is true if at least one input is true.
