What is the definition of multiplexer?
A multiplexer is a device or system commonly used in both analog and digital applications. It is also called a muldex, muldem or mux, depending on the specific application and regional standards.FunctionMultiplexers isolate or convert several input signals into a single output signal.In ElectronicsElectronic multiplexers exist in digital circuits, allowing logical gates to control signal flow, and in control components that act as switches for electronic equipment. On schematics, the symbol for a multiplexer is an isosceles triangle.In TelecommunicationsSeveral communications channels enter a multiplexer on the input side, while a single channel transmits from the output side. Time division multiplexers (TDM) convert portions of several input lines into one wide-band analog signal called a pulse amplitude modulated (PAM) signal in certain systems.DemultiplexersA demultiplexer takes one input signal and sends it through multiple output lines. Multiplexers often include a demultiplexer a
