FDM has two disadvantages:
- First, since the various frequency bands must be separated by guard bands, there can be bandwidth wastage.
- Second, if there are significant nonlinearities in the transmission link, there could be crosstalk among the different signals, resulting in communication errors.

What is the disadvantage of frequency division multiplexing FDM?
Frequency Division Multiplexing Disadvantages
FDM requires more hardware than TDM. The Frequency Division Multiplexing system extremely expensive. There is intermodulation distortion that occurs in FDM. There is a need for a large number of system modulators and filters in FDM.
Which of the following is one of the disadvantages of frequency division multiplexing Mcq?
Disadvantages of FDM:
FDM is only used only when a few low-speed channels are desired. Intermodulation distortion takes place. The circuitry for FDM is more complex than TDM. FDM requires more hardware than TDM.
What is a disadvantage of time division multiplexing TDM )?
Time division multiplexing (TDM) has its disadvantages. The main disadvantage is that synchronization is necessary for TDM to work. This can be difficult to implement, especially if the channels are widely spaced in frequency. Another disadvantage is that all TDM channels could be wiped out by slow, narrowband fading.
