A truth table is a mathematical table used in logic, specifically in connection with Boolean algebra, Boolean functions, and propositional calculus. It sets out the functional values of logical expressions on each of their functional arguments, that is, for each combination of values taken by their logical variables12.
Construction of a Truth Table
To construct a truth table for a given logical expression, follow these steps:
Identify Input Variables: Determine the number of input variables.
List All Possible Combinations: For n input variables, there will be 2^n possible combinations.
Determine the Output: Calculate the output for each combination using the logical expression1.
Example: AND Operation
For an AND operation with two variables A and B, the truth table is as follows:
| A | B | A ∧ B ||---|---|-------|| 0 | 0 | 0 || 0 | 1 | 0 || 1 | 0 | 0 || 1 | 1 | 1 |Example: OR Operation
For an OR operation with two variables A and B, the truth table is as follows:
