Question 17

What is the output of a NOT gate

Answer 17

An inverter has only one input, and the output is always the opposite of the input

Question 18

When does an AND gate produce a logic 1?

Answer 18

When all inputs are at logic 1

Question 19

When does a NAND gate produce logic 1?

Answer 19

The output logic is 1 when any output is 0

Question 20

When does a NAND gate produce logic 0?

Answer 20

The output is a logic 0 only when all inputs are 1

Question 21

When does a OR gate produce logic 1?

Answer 21

If any of the logic inputs are logic 1

Question 22

When does a NOR gate produce logic 1?

Answer 22

The output logic is only logic 1 if all input logics are at logic 1

Question 23

When does a XNOR gate produce logic 1?

Answer 23

The output is at logic 1 when both inputs are at logic 0 or both inputs are at logic 1
