It accepts the binary information from several input lines or sources and depending on the set of select lines, a particular input line is routed onto a single output line. It is a Combinational Logic Circuit with more than one input line, one output line and more than one select line. The multiplexer or MUX is a digital switch, also called as data selector. In this article we are going to discuss about types of multiplexers and its design.

These are found in many digital system applications such as data selection and data routing, logic function generators, digital counters with multiplexed displays, telephone network, communication systems, waveform generators, etc. A basic multiplexer has various data input lines and a single output line. These are mostly used to form a selected path between multiple sources and a single destination. A multiplexer is the most frequently used combinational circuit and it is an important building block in many in digital systems. Let us focus on digital signals in this tutorial, to keep things simple. Multiplexers are used for both Analog and Digital signals. The device which is responsible for Multiplexing is known as Multiplexer. Two of the best examples of Multiplexing Systems used in our day-to-day life are the landline telephone network and the Cable TV. The three common types of Multiplexing approaches are: For cost-effective and efficient use of a channel, the concept of Multiplexing is very useful as it allows multiple users to share a single channel in a logical way. In analog communication systems, a communication channel is a scarce quantity, which must be properly used.

Multiplexing is the process of combining one or more signals and transmitting on a single channel.
