Multiplexer
A multiplexer is an electronic device that selects one of several input signals and forwards the chosen input to a single output line. It acts like a digital switch, allowing multiple data sources to share a single communication channel. This is useful in various applications, such as data routing and signal processing.
Multiplexers are often used in conjunction with other components, such as demultiplexers, which perform the reverse function by taking a single input and distributing it to multiple outputs. They are essential in telecommunications, computer networks, and digital circuits, helping to optimize resource usage and improve efficiency.
