Which term refers to a logic gate that reverses its input logic level?

The term that refers to a logic gate that reverses its input logic level is the inverter. An inverter, also known as a NOT gate, performs a fundamental operation by converting a logical 1 (true) to a logical 0 (false), and vice versa. This means that if the input is high, the output will be low, and if the input is low, the output will be high.

In digital circuits, inverters are crucial for manipulating logical signals, allowing for more complex operations and interactions between different components. They are widely used in various applications, such as signal conditioning and creating more sophisticated logical expressions by negating inputs.

The other options represent different types of logic gates that serve different functions: a buffer reinforces a signal without changing its logic level, while AND and OR gates perform specific operations based on their inputs but do not inherently reverse the logic level.
