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.
How does the truch table calculator works?
dCode interprets the Boolean logical expression and calculates, using Boolean algebra, all the possible combinations of 0 and 1 for each variable (among the Boolean variables requested) in order to make the truth table.
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 |
