Logic Gates Quiz

What is the basic function of an AND gate?

• To output true when all inputs are false.

• To output true when any input is true.

• To output false only when all inputs are false.

• To output true only when all inputs are true.

Provide the truth table for an OR gate.

• A=0, B=0 -> Output=0; A=0, B=1 -> Output=1; A=1, B=0 -> Output=1; A=1, B=1 -> Output=1

• A=0, B=0 -> Output=0; A=0, B=1 -> Output=0; A=1, B=0 -> Output=0; A=1, B=1 -> Output=0

• A=0, B=0 -> Output=1; A=0, B=1 -> Output=0; A=1, B=0 -> Output=0; A=1, B=1 -> Output=0

• A=0, B=0 -> Output=1; A=0, B=1 -> Output=1; A=1, B=0 -> Output=0; A=1, B=1 -> Output=0

What symbol is used to represent a NOT gate?

• Square with a line

• Inverted triangle with a small circle

• Triangle with a line

• Circle with a dot inside

Give an example of an application for an XOR gate.

• Error detection and correction codes in data transmission systems

• Data encryption in secure communication

• Temperature control in a thermostat

• Signal amplification in audio systems

What does XNOR gate stand for?

• Exclusive NOR

• AND

• NAND

• Exclusive OR

Explain the purpose of a BUFFER gate.

• The purpose of a BUFFER gate is to reduce the input signal strength

• BUFFER gates are used to invert the input signal

• BUFFER gates are designed to combine multiple input signals

• The purpose of a BUFFER gate is to amplify the input signal without changing its logic level.

What is the output of a NAND gate if both inputs are 1?

• 1

• 3

• 0

• 2

How many inputs does an XOR gate typically have?

• 4

• 3

• 5

• 2

Draw the symbol for an OR gate.

• The symbol for an OR gate is a straight line with a circle at the end and two inputs on the sides.

• The symbol for an OR gate is a curved line with a point at the bottom and two inputs on the sides.

• The symbol for an OR gate is a triangle with two inputs on the sides.

• The symbol for an OR gate is a square with two inputs on the sides.

In what scenario would you use a NOT gate?

• When you need to delay the input signal.

• When you need to combine multiple input signals.

• When you need to invert the input signal.

• When you need to amplify the input signal.
