What are Digital and Analog Communication Systems?
Digital and analog communication systems are two types of communication systems that are used to transmit and receive information over a medium, such as a wire, a cable, or a wireless channel. Digital communication systems use discrete signals, such as binary digits (0 or 1), to represent information, while analog communication systems use continuous signals, such as voltage or current, to represent information. Digital communication systems have some advantages over analog communication systems, such as higher noise immunity, higher data rate, lower error rate, and easier encryption and compression. However, analog communication systems have some advantages over digital communication systems, such as lower cost, lower complexity, and better compatibility with natural signals.
