The correct answer is: C. Truth
A truth table is a mathematical table used in logic to show the functional values of logical expressions on each of their functional arguments, that is, for each combination of values taken by their logical variables. In particular, truth tables can be used to show whether a propositional expression is true for all legitimate input values, that is, logically valid.
Truth tables can be used to design digital
circuits. The first step in designing a digital circuit is to create a truth table for the circuit. The truth table will show the inputs and outputs of the circuit for each possible combination of inputs. Once the truth table is created, the next step is to design the logic gates that will implement the circuit. The logic gates will be connected together in a way that will produce the desired outputs for each possible combination of inputs.The other options are incorrect because they do not describe the type of table that is used in digital design. A standard table is a table that is used to compare different things. A two-stage table is a table that has two stages. A two-dimensional table is a table that has two dimensions. None of these tables are used in digital design.
