What does FDM mean?

Ever wonder how complex the connectivity and network system is when you are on your smartphone devices? The FDM is one such divisive nonoverlapping network connectivity system that travels with separate signals. Through this article, know what does FDM stands for! Its uses and how it works! By the end of the article, you surely will understand the complexity associated with connectivity.

What does FDM stand for?

The FDM full form is Frequency Division Multiplexing which helps in dividing the sum of available bandwidth in nonoverlapping series of frequency bands. Every single frequency band transmits a separate signal. Due to this sharing procedure, a single transmission medium like optical fiber is enabled to carry numerous independent signals. To bring clarity to the stated situation, you can think of the broadcasted television. In your cable television, multiple channels run through a single cable.

Where and in which devices or applications FDMs are majorly used? 

Frequency Division Multiplexing (FDM full form) is majorly used by different small and large business houses for ensuring smooth connectivity.

1. FDM for small business houses. 

Many small business houses often use FDM for their internet connectivity. An Analog internet connection in the form of twisted cable pair is used for reliable data transfer with 3 kHz bandwidth. The type of bandwidth used by small business houses is shorter as compared to the larger firms.

2. Large business houses and FDM. 

Not only larger business houses but government offices also use larger bandwidth for connectivity. There FDM usually transmits signals via copper cable popularly known as fiber optic cable. It helps in disseminating numerous signals which are free from dependency to get used by the users.

3. Applications that allow FDM transmission. 

For multiplex calls over telephonic networks, FDM is a popular choice. Some of the applications through which Frequency Division Multiplexing ( FDM full form) is used include –

• Both AM and FM radio transmission.
• FDM transmission through TV broadcasting.
• Wireless networking system.
• Through cellular and satellite telecommunications.

How does FDM work? 

As of now, it is clear that Frequency Division Multiplexing ( FDM full form ) combines multiple signals on a single communication line, and then it transmits in different frequencies to different sub-channels.

The successful transmission without interference on a single line becomes possible through the separation of FDM in the form of unused frequency strips. These unused frequency strips are known in the name of guard bands. The primary moto of these bands is to restrict the overlapping of these signal frequencies on the transmitted medium.

The signal that is being generated or modulated to some extent from the sending device is transmitted across other diversified bands. And the modulated signals with the help of a multiplexer are used to combine the signals. And at the end carries them via the communication channel. The process ends when the carried signals are extracted by individual signals with the assistance of demultiplexers.

Pros of FDM.

The Frequency Division Modulation (FDM full form) is widely used for broadcasting and importing information through telephonic communication. Some of the unmissable pros of FDM are-

• The demodulation process of FDM makes it an easier medium.
• The expense behind FDM is not much.
• The latency of FDM is much more compared to TDM.
• For analog signals, you can highly trust FDM.
• With FDM one can transmit multiple signals at one particular point in time.
• No synchronization is demanded between the sender and the receiver.

All in all, FDM has proven to be more reliable as compared to other multiplexing mediums like TDM.

Are there any limitations related to FDM? 

The Frequency Division Multiplexing (FDM full form) has proven to be one of the speediest ways of transmitting signals. And its greatest good is the speed at which it carries the signal. But at the same time, one can’t ignore the fact that for long-distance signal supply, larger bandwidth is essential. And this becomes a serious issue if the system performance does not encompass proper engineering.

Some of the loopholes that make FDM a matter of second thought in terms of sharing signals are-

• There is a greater probability of bandwidth wastage due to the separation of frequency bands with the support of guard bands.
• The issue of communication error is also undeniable when there is nonlinearity in transmission links. It creates the chances of crosstalk in between multiple signals.
• Thirdly, since FDM majorly uses analog signals, there are higher possibilities of noise disruptions. These noise disruptions are less likely for digital signals.

However, all these drawbacks are quite adjustable as compared to their pros. And mainly due to this reason FDMs are adopted by devices and applications.

FDM vs TDM.

Multiplexing bits of information from several incoming communications and then articulated in the form of a single outgoing communication network-based bit time. Based on the above definition, you can find two main types of multiplexing. And those are –

• The TDM means Time-division multiplexing.
• The FDM full form Frequency Division Multiplexing.

In TDM the signals which are transmitted can be both digitals as well as analogous. As compared to FDMs which only work in the form of analog signals. Besides that, the conflicting chances of FDM are higher than TDM. The transmitting activity in FDM is based on frequency length.

Compared to that, the signals which are shared in TDM are sent based on time intervals. The synchronization pulse is essential for the TDM. But as shared earlier, FDM works based on Guard band. It is visible that TDM is much more efficient than FDM when it comes to workability.

Sum up. 

Thus, the above article must have made your conception clear on What does FDM stands for! Its advantages and how it works! To sum up, multiple signals can be transmitted in FDM without any synchronization. Other than that, the process of signal transmission through FDM is not that expensive as compared to TDM.
