Question
What is a truth table?
Answer Options
- A) A list of inputs and corresponding outputs for an op-amp
- B) A list of inputs and corresponding outputs for a digital device
- 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
Correct Answer: B
Explanation
A truth table is the fundamental tool used to define and analyze the operation of any digital logic circuit. It provides a concise summary of the circuit’s function regardless of its complexity or internal design.
A truth table is formally defined as a list of inputs and corresponding outputs for a digital device. The table lists every possible combination of input values (e.g., 00, 01, 10, 11 for two inputs) and specifies the resulting output value (0 or 1) for each combination, completely defining the logic being performed.
