The computer that can input analog signals and return result in digital form

The computer device or system that can receive analog signals and convert those signals into a digital form for processing is commonly known as an Analog-to-Digital Converter (ADC). The ADC plays a critical role in enabling computers to interact with the analog world, as computers inherently process digital information. This functionality is essential in numerous applications, including digital audio recording, sensor data processing, and various forms of data acquisition where the initial real-world signal is analog.
