What is the main function of a negator in digital logic?

The main function of a negator, often referred to as a NOT gate in digital logic, is to invert input signals. This means that when a negator receives an input signal of a certain state, it outputs the opposite state; for example, if the input is high (1), the output will be low (0), and vice versa. This fundamental operation of inverting signals is crucial in various digital circuits for tasks such as control logic, data processing, and implementing logic functions. It plays a significant role in creating more complex logical expressions and systems by allowing for the manipulation of binary values, thereby supporting various computing applications.
