G12 - Logic Gates and Processing

Is a device that acts as a building block in digital circuits

They perform basic logical functions

• logical operators

• logical gate

• Logical circuits

What does the NOT gate do?

• It changes every binary signal into its opposite.

• It outputs the same signal.

• It only works with one input.

• It is used to connect multiple circuits.

What is the output of the AND gate when both inputs are True?

• True

• False

• It depends on the circuit.

• It outputs 0.

What does the NAND gate output when both inputs are True?

• True

• False

• It outputs 1.

• It outputs 0.

What is the output of the OR gate if at least one input is 1?

• 1

• 0

• It depends on the circuit.

• It outputs both inputs.

What does the NOR gate output when both inputs are 0?

• 1

• 0

• It outputs both inputs.

• It depends on the circuit.

What is the output of the XOR gate when both inputs are 1?

• 1

• 0

• It depends on the circuit.

• It outputs both inputs.
