  2. A list of inputs and corresponding outputs for a digital deviceCorrect answer
  3. A diagram showing logic states when the digital gate output is true
  4. A table of logic symbols that indicate the logic states of an op-amp

Explanation

A truth table enumerates every possible combination of input logic states for a digital device together with the output state that results, so it defines the device's function completely without reference to its internal circuitry.
