What is a truth table?
- A.A list of inputs and corresponding outputs for an op-amp
- B.A list of inputs and corresponding outputs for a digital device (correct answer)
- C.A diagram showing logic states when the digital gate output is true
- D.A table of logic symbols that indicate the logic states of an op-amp
WhyA truth table is a list of inputs and corresponding outputs for a digital device. A truth table lists every possible combination of inputs to a digital device along with the corresponding output for each combination, a complete tabular description of the device's logical behavior, answer B. It isn't specific to op-amps, which are analog devices without discrete logic states, and it isn't a diagram of gate states or a symbol table, a truth table is specifically an input/output listing.
