Multiplexing is the combining of many signals into a single signal. This combination is done over a shared medium. When an analog signal is multiplexed, the process is known as Analog Multiplexing. Also, when a digital signal is multiplexed, it is known as a digital multiplexing process. The multiplexing process breaks a communication channel into many logical channels. Each of the logical channels is set aside for a particular message signal to be transferred. Multiplexing is carried out by a device known as MUX. On the other hand, a DEMUX is a device responsible for demultiplexing. Digital and analog are the major types of multiplexers.
