With the NOT logic gate, if the input is ON then the output will be ______.

The NOT logic gate, also known as an inverter, operates based on a fundamental principle of logic where it reverses the state of its input. If the input to a NOT gate is ON, which generally corresponds to a binary value of 1, the output will be OFF, represented by a binary value of 0.

This behavior is a key characteristic of NOT gates, showcasing how they affect the logic level. Thus, when the input is ON, the NOT gate inverts this to OFF, making it a simple yet vital component in digital logic circuits. Understanding this inversion is essential for working with more complex logic structures, as it underpins how multiple gates can be combined to create desired functions in computing and electronics.
