5.5 Logic

Question 1

Logic gates have three basic functions what are they?

Answer 1

AND function
OR function
NOT function

Question 2

The Not gate acts as an…..

Answer 2

Inverter

Question 3

How does an AND gate work?

Answer 3

You will only get an output of 1 if both inputs are 1. If the inputs are 1 and 0 the output will be 0.

Question 4

How does an OR gate work?

Answer 4

If either inputs is 1 then you get a 1 as the output

Question 5

How does an NOR gate work?

Answer 5

If either input has a 1 then the output is 0 (it works in an opposite manner to an OR gate)

Question 6

How does an XOR gate work?

Answer 6

If you inputs are not identical then the output is 0 if both the inputs are different from each other then the output will be 1

Question 7

How does an XNOR gate work?

Answer 7

If both inputs are identical then you will get an output of 1. If the inputs are different then you will get a 0.

Question 8

Not gates (Inverters) have how many inputs?

Answer 8

1

Question 9

What are Gates used for?

Answer 9

Failure detection and isolation
