truth table

[′trüth ‚tā·bəl]
(mathematics)
A table listing statements concerning an event and their respective truth values.

truth table

(logic)
A table listing all possible combinations of inputs and the corresponding output of a Boolean function such as AND, OR, NOT, IMPLIES, XOR, NAND, NOR. Truth tables can be used as a means of representing a function or as an aid in designing a circuit to implement it.

truth table

A chart of a logical operation's inputs and outputs. The following example is a Boolean NAND truth table.

Those familiar with Simulink[R] may ask "Why not use the built-in truth table function instead of manually constructing a TT from transitions and junction blocks?" To illustrate, the figure below shows the TT implemented using the built-in Truth Table Object (TTO) in Simulink/Stateflow[R]:
