Nondigital refers to a type of technology that does not involve the use of digital components. ANALOG is a term used to describe this type of technology, which uses physical components such as wires and transistors to create a signal. ANALOG technology is often used in audio and video equipment, as well as in some medical devices. It is also used in some communication systems, such as radio and television broadcasting. Nondigital technology is becoming less common as digital technology becomes more prevalent.
