What is Multiplexing?

Multiplexing is a technique that allows the simultaneous transmission of multiple signals through a single channel or link.
In multiplexing, several signals are combined into a single composite signal and transmitted over a single channel or medium.
Using multiplexing the channel bandwidth can be utilized more efficiently or more signals can be transmitted through a channel at the same time.

Types of Multiplexing:
1. Frequency Division Multiplexing (FDM)
2. Time Division Multiplexing (TDM)
3. Wavelength Division Multiplexing (WDM)

What is Frequency Division Multiplexing

In Frequency Division Multiplexing, the different message signals are modulated at the different carrier frequencies. In this way, the modulated signals are separate from each other in the frequency domain.
The modulated signals are combined together to form the composite signal and this signal is sent over the shared medium or channel.

Applications of Frequency Division Multiplexing Technique:
1) AM and FM radio Broadcast
2) Cable TV
3) Satellite Communication
4) Telemetry
5) Telephony Systems
6) Early Generation Cellular Networks

This video will be helpful to all the students of science and engineering in understanding the Frequency Division Multiplexing (FDM) technique.

Once I get a job I will support this channel like heck

[selvajothehaca]

One of the best channels I've ever watched. It really helped me to understand a lot. Thank you

[VarunKaushik]

Taught better than most people in the world!

[tushargoyal]

Through animation it is easy to
Thank you for the last movement to explain

[alimran]

Thanks for your nice explanation. The animation in this your video helped me out so much. Your step-by-step explain made me understand well.

[jayningulkar]

What an Coincidence I was just studying about multiplexing and the video got uploaded 😀

[raya]

Omg my two years of wasted corona time got cleared i can pass in bifocal electronics tysm ✨✨😭😭😭

[avijitghosal]

This video was very satisfying to watch, thanks for your contribution

[valentinvalenciavalencia]

Muchas gracias, Thank you very much, this is a wonderful explanation for beginners in telecommunications like me

[sabinbasnet]

what about TDM? very dissapointed, your video is very good and helpful, but please cover the related topic thats the least we expect

[alloc]

Please complete analog and digital communication playlist
There are no digital communication content

[jbkrobin]

Why do you sound like you are just reading it off of a slide?

[surajsolanke]

Sir, will you please tell which softwares you use for such animations (screen transitions). These are amazing.

[jwnglarigoyari]

need video on Frequency modulation and phase modulation

[Loolieok]

if i assign form 0 to 4khz m1 and form 8khz to 12khz m2, m2 will trasmit more bits than m1?

[rajeshb]

Is mobile infra works on frequency division multiplexing ?

[WiredStudy]

Transmit two signals of frequencies 1 kHz and 2 kHz through a PCM system using multiplexing technique.

Sir, will you please tell which softwares you use for such animations (screen transitions). These are amazing.
