Analog Circuit

An analog circuit processes continuous signals, which can vary smoothly over time. Unlike digital circuits that handle discrete values (like on/off), analog circuits represent information through variations in voltage, current, or resistance. This allows them to handle real-world phenomena such as sound, light, and temperature more naturally. Common examples include audio amplifiers, radios, and sensors. The design and function of analog circuits enable them to effectively capture and manipulate the nuances of these varying signals, making them essential in many electronic devices and systems.
