Multiplexed Communication Systems

Multiplexed communication systems are technologies that allow multiple signals or data streams to be transmitted simultaneously over a single communication channel. This technique helps maximize the use of the available bandwidth, making communication more efficient. For example, in telephone lines, multiple calls can occur at the same time without interference. This is achieved through various methods, such as time division (where each signal takes turns), frequency division (assigning different frequencies to different signals), or code division (using unique codes for each signal). Overall, multiplexing enhances the capacity and efficiency of communication networks.
