Detailed explanation-1: -There are mainly two types of multiplexers: analog and digital. If the analog signals are multiplexed, then it is called as analog multiplexing. If the digital signals are multiplexed, then it is called digital multiplexing.

Detailed explanation-2: -Multiplexing is widely used in telephony, data communications, and audio/video broadcasting. Telephone service typically use multiplexors to combine the various lines in a neighborhood into a single signal that is then carried to the central switching office for routing and call management.

Detailed explanation-3: -If a device does not have data for a particular time slot, then the empty slot will be transmitted. The most popular Synchronous TDM are T-1 multiplexing, ISDN multiplexing, and SONET multiplexing. If there are n devices, then there are n slots.

Detailed explanation-4: -Multiplexing is the process of combining multiple signals into one signal, over a shared medium. If analog signals are multiplexed, it is Analog Multiplexing and if digital signals are multiplexed, that process is Digital Multiplexing.
