A demultiplexer is the counterpart to the multiplexer. This time the telephone line is at the input. The demultiplexer connects the telephone line to one of a variety of telephones. In this way, you connect two phones in a phone call. In a communication system, you find generally both multiplexer and demultiplexer.
On the following pages you get to know the multiplexer and demultiplexer. Thereby you build the circuits with logic gates and you can switch both digital and analog signals.
Before you can start with the flip-flop experiments, you have to make a few preparations...
