What will a NOT gate output if the input is low?

A NOT gate, also known as an inverter, is a fundamental digital logic gate that performs the operation of negation on the input signal. When the input to a NOT gate is low, which corresponds to a logic level of 0 volts or a binary value of 0, the NOT gate inverts this input. The output will be the opposite of the input. Therefore, if the input is low, the NOT gate outputs high, equivalent to 1.

This behavior is foundational in digital logic design, where inverted signals are often used in combination with other logic gates to perform various functions in circuit design. High output, in this context, represents the logic level corresponding to a signal that actively conveys a true or high state in digital logic. Understanding the operation of NOT gates is essential for grasping more complex digital systems and circuits.
