This document is a presentation on multiplexing techniques. It defines multiplexing as a technique that allows sending multiple signals over a single data link by sharing the medium. It describes three main multiplexing types: frequency division multiplexing (FDM) which modulates each input signal to a different carrier frequency; wavelength division multiplexing (WDM) which combines multiple wavelengths of an optical signal; and time division multiplexing (TDM) which assigns each transmitter a time slot. TDM is further broken down into synchronous and asynchronous types. Diagrams are included to illustrate each technique.

5. Multiplexing
• Multiplexing :-
Multiplexing is a
technique which allows sending
multiple signals over a single data link.
In simple words, Sharing of the
medium between multiple signals

8. FDM Frequency Division Mux
• FDM is an analog multiplexing
technique. Every input signal is
modulated with a carrier frequency
to change its characteristics
(Frequency).

10. WDM Wavelength division mux.
• It is an analog technique.It combines
multiple wavelengths of an optical
signal to transmit in a single optical
fiber.

12. TDM Time division Mux
• TDM is a digital mux technique. Every
transmitter is assigned a time slot to
transmit its signal. We have already
discussed its application in E1 and T1
lines.
Synchronous TDM
Asynchronous TDM
