Study Notes
Multiplexing
- Multiplexing is a method used to divide a medium for multiple signals to share one bandwidth.
Purpose of Multiplexing
- The purpose of multiplexing is to allow multiple signals to share the same communication channel, increasing the efficiency of the channel.
Types of Multiplexing
- The oldest multiplexing technique is Frequency Division Multiplexing (FDM).
Application in Telecoms
- In telecoms, multiplexing is used to carry several telephone calls using one wire.
Aim of Multiplexing
- The aim of multiplexing is to enable simultaneous transmission of multiple signals over a single communication channel.
