In NEMA logic, a(n) ____ is used to show that a gate is inverted.

In NEMA logic, the symbol that indicates a gate is inverted is represented by the letter “X.” This notation is used to clearly signify that the output of a gate is NOT the same as its input, which reflects the operation of an inverter or a logic gate that performs negation.

The use of the letter "X" creates an immediate visual cue for engineers and designers, allowing them to quickly identify inverted signals when interpreting logic diagrams. In digital electronics, understanding how inverters function is crucial, as they play a vital role in constructing complex circuits from basic logic gates. This knowledge is foundational for anyone studying digital systems or circuit design.
