Introduction. Under the simplest conditions, a medium can carry only one signal at any moment in time. For multiple signals to share one medium, the medium must somehow be divided, giving each signal a portion of the total bandwidth.. Lecture 2: History. (Hint: Al Gore is not involved).

Most common use of multiplexing is in long-haul communication using coaxial cable, microwave and optical . The process of combining the data streams is known as multiplexing and hardware used for multiplexing is known as a multiplexer.. Multiplexing is achieved by using a device called Multiplexer (.
