A/D converters

An A/D (Analog-to-Digital) converter transforms continuous analog signals, like sound or temperature, into digital data that computers can process. It samples the analog signal at regular intervals and measures its voltage level, then converts each measurement into a digital number. This process allows the analog world to be represented in a format suitable for digital devices, enabling tasks like recording audio, reading sensors, or transmitting data. Think of it as a device that captures real-world signals and turns them into a series of numbers the computer can understand and work with accurately.
