Why truth table is used?

Question

options are:
a. to get output true/false
b. to get output 1 and 0
c. to get electrical circuit output

Answer 1

None of those are very good answers.

A truth table is most typically used to show the relationship between inputs and outputs of a logic circuit.

Note Knowing the outputs without reference to the inputs would be useless.

Answer 2

Truth Table nothing but a table which associates
Input Logic and output Logic.


You have a set of Inputs which can take different Logical values
and you have a set of outputs.

The Truth Table associates, the various combination of Input Logic values and the corresponding Output Logic values.

Like in this ex. I have 2 inputs A and B and one Output C
a truth table can look like this

A B C

0 0 1

0 1 1

1 0 0

1 1 0

Here 1 indicates Logic True
0 indicates Logic false

Answer 3

Hi. It can be all three but usually it is used in an electrical logic diagram.

Answer 4

all of the abvove.

truth table is also used to prove or determine the outcome
of logic expressions.
