Analog-to-Digital Converter

An Analog-to-Digital Converter (ADC) is a device that transforms continuous, real-world signals—such as sound, temperature, or light—into digital data that computers can process. It samples the analog signal at regular intervals and measures its amplitude, then converts these measurements into binary numbers (ones and zeros). This allows digital devices to interpret, store, and analyze physical signals accurately. In essence, an ADC bridges the gap between the analog world and digital systems by translating continuous signals into a format that computers can understand and work with efficiently.
