Amp Up Your Knowledge: 2026 Electronics Engineering Board Exam Bash!

The correct answer is the truth table. A truth table is a systematic way to represent the output states of a logic gate or digital circuit for all possible combinations of its input states. Each row of the truth table corresponds to a unique combination of input values and showcases the resulting output, thereby providing a clear and organized view of how the logic circuit operates under different scenarios.

Truth tables serve as essential tools in digital logic design and analysis, allowing engineers and students to easily identify how various inputs affect the system's output. By outlining every possible input-output pair, a truth table ensures that the logic functionality is conveyed accurately and comprehensively.

The other choices, such as flowchart, logic diagram, and state diagram, serve different purposes in the field of electronics and computer science. A flowchart outlines a process or algorithm through symbols and arrows, while a logic diagram visually represents the logical relationships between multiple inputs and outputs using graphical symbols for gates. A state diagram is used in state machine design to represent the states of a system and their transitions but does not focus on output combinations from logical inputs like a truth table does.
