Multiplexer

A multiplexer, or "mux," is a device that combines multiple input signals into one output signal. Think of it like a switchboard operator directing phone calls. It takes several data sources, like audio or video signals, and uses a selector to choose which one to send to the output at any given time. This allows efficient use of data pathways and helps in managing bandwidth. Multiplexers are commonly used in telecommunications and digital circuits, making it easier to transmit and process multiple data streams without interference.
