Analog-to-Digital Converter (ADC)

An Analog-to-Digital Converter (ADC) is a device that transforms continuous analog signals—like sound, light, or temperature—into digital data that computers can process. It does this by sampling the analog signal's voltage at regular intervals and then quantizing these samples into discrete values, effectively converting a smooth, variable signal into a series of fixed numbers. This process allows electronic systems and computers to interpret, analyze, and store real-world information captured from sensors or other sources in a format they can work with efficiently.
