Signal converters are devices that change one type of signal into another, allowing different systems to communicate effectively. For example, they can convert analog signals, like those from a microphone, into digital signals that a computer can process. This conversion is essential in various applications, including audio and video equipment, telecommunications, and data transmission. These converters come in various forms, such as analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). Each type serves a specific purpose, ensuring that signals maintain their integrity during the conversion process. By facilitating compatibility between different technologies, signal converters play a crucial role in modern electronics.
