Multiplexing Techniques and Carrier Systems Quiz

The four basic approaches to multiplexing are Frequency Division Multiplexing (FDM), Wavelength Division Multiplexing (WDM), Time Division Multiplexing (TDM), and Code Division Multiplexing (CDM).

The purpose of multiplexing is to combine information streams from multiple sources for transmission over a shared medium.

Frequency Division Multiplexing (FDM) is a multiplexing technique that combines multiple signals by assigning each signal a different frequency band.
