What is the output of a low input when applied to an inverter?

In digital logic, an inverter, also known as a NOT gate, is a fundamental component that outputs the opposite value of its input. When a low input, which represents a binary value of 0, is applied to the inverter, it produces a high output, which corresponds to a binary value of 1.

This operation is based on the basic principle of logical negation: the inverter simply flips the input signal. Therefore, because a low input translates to a high output in the case of an inverter, the correct output for a low input signal is indeed a high output.

The other options do not align with the functionality of an inverter. A low output would suggest that the inverter is behaving like a buffer, which it does not. A neutral output does not exist in this context, as digital devices operate with clear high or low states. Lastly, the concept of no output would imply that the inverter is not functioning, which is contrary to the expected behavior of a digital logic gate designed to provide an output based on its input.
