What is a NOT Gate?NOT Gate DefinitionA NOT gate, also known as an inverter, is a basic digital logic gate that produces an output which is the opposite of its input.Symbol and Truth TableThe symbol for a NOT gate reflects its function of inverting the input signal, with a truth table confirming its consistent output inversion.Circuit DiagramA simple bipolar transistor setup demonstrates the NOT gate’s working principle, where it inverts the input signal.Working PrincipleThe NOT gate operates by
