What is the primary function of an inverter in digital circuits?

The primary function of an inverter in digital circuits is to perform the NOT logic function. An inverter takes a single input and outputs the opposite value. For example, if the input is a logic high (1), the inverter will output a logic low (0), and vice versa. This behavior is fundamental to the operation of digital systems, providing essential capabilities for signal processing, logic design, and circuit functionality.

Understanding the inverter's role as a NOT gate is crucial, as it allows the construction of more complex logic functions by combining multiple gates, which is the foundation of digital circuit design. The successful application of inverters is vital in creating flip-flops, multiplexers, and other essential components of digital electronics, emphasizing their importance in the field.
