Analog Switch Multiplexer
Analog Switch Multiplexer or “MUX” is a device which function is to selects one of several analogue or digital input signals, and then forwards the selected input to a single line output. Multiplexers are mainly used to increase the bandwidth of the signals over a network or connection, in short allowing multiple devices or sources to share the same input to another functional block. Another use is of course to implement Boolean logical functions, within a design. The opposite of the “MUX” is a “DEMUX” or demultiplexer which will take many output signals into a single input. Normally a “DEMUX” is on the “other end” of a “MUX”. Applications are varied of this type of device.
