Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between FDM and TDM. There are 2 commonly used techniques for multiplexing and the first one is TDM and second one TDM. The basic difference between them is that in FDM numerous signals are transferred with the different frequency slots. While in TDM signals are transferred through different time slots.

Multiplexing is a technique through which numerous signal is transmitted in a common channel. In today’s post, we will have a detailed look at both FDM and TDM to compare them and find their differences. So let’s get started with Difference Between FDM and TDM.

Difference Between FDM and TDM

FDM

It is the method through which the net bandwidth of a single is parted in different frequency levels and every band has its on the signal.
It helps to convert a single medium used for transmission to make different mediums.
It sends data in parallel combination

The practical example of this method is radio signal transmission and tv transmission.
Ther is cable tv is also its example through which numerous channels are operated.
It uses analog multiplexing techniques.
It does not need any synchronization.
Its circuit arrangement is complicated.
There is crosstalk is existing.
In a telephone system, it used to transmit calls over multiple users.
There is a similar technique to this called wavelength division multiplexing that uses optic fiber for communication
The full form of FDM is Frequency Division Multiplexing.
Its propagating delay is sensitive.
Its efficiency is less.
Its price is high.

TDM

The method that allows the transmission of numerous signals of data through the common line in different time slots is called TDM.
Its full form is Time Division Multiplexing.
It is a digital technique that operates on the time in place of frequency to distinct data from another form of data.
It used to transmit 2 or more two signals through a single source.
It employed when the bit ratio of the signal source larger than the signal sent.
It was first time used in the nineteenth century for telegraphy.

It required synchronization.
Its circuit is less complicated than the FDM.
In this signal transmission, there is no need for crosstalk.
Its efficiency is larger than the FDM.
Its price is less than FDM.
It normally used for digital signal but also work for the analog signal
In this module, the time domain is parted in different time slots having a certain value.
In this signal transmission, a digital multiplexing technique is used.
