Answers to Questions
What is a truth table?
A truth table is a table representing the output boolean values of a logical expression based on their entries. The table thus presents all the possible combinations of the input logical variables (generally 0 / FALSE and 1 / TRUE) and the result of the equation as output.
Example: The table of the logical NOT function:
| A | NOT A |
|---|---|
| 0 | 1 |
| 1 | 0 |
Every electronic circuit is associated with a truth table which describes it.
What is the truth table for logical AND?
The truth table for the AND function is:
| A | B | A AND B |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
What is the truth table for logical OR?
The truth table for the OR function is:
| A | B | A OR B |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
What is the truth table for logical XOR?
What is the truth table for logical NAND?
The truth table for the NAND function is:
| A | B | A NAND B |
|---|---|---|
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
What is the truth table for logical NOR?
The truth table for the NOR function is:
| A | B | A NOR B |
|---|---|---|
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 0 |
