ADC (Analog-to-Digital Converter)

An Analog-to-Digital Converter (ADC) is a device that transforms real-world analog signals, like sound or temperature, into digital data that computers can process. It samples the continuous analog signal at regular intervals and measures its voltage or amplitude. These measurements are then converted into a series of binary numbers, enabling precise digital representation. ADCs are essential in electronics for connecting real-world sensors with digital systems, allowing devices like smartphones, microphones, and medical instruments to interpret and work with physical signals accurately.
