A multiplexer combines multiple signals into a single output signal by assigning a unique channel to each input signal. This allows for efficient use of transmission media such as fibers, wires or radio waves. A modem is a device that modulates digital signals to be transmitted over analog media and demodulates them upon reception. A switch connects devices in a network and determines how to route data packets between them. None of these devices specifically combine data from multiple sources into a single output signal.
