Advantages, disadvantages and applications of frequency division multiplexing (FDM)

Advantages:

There are some advantages of frequency division multiplexing(FDM) which are given below,

• It does not need synchronization between its transmitter and receiver.
• Frequency division multiplexing (FDM) is simpler and easy demodulation.
• Due to slow narrow band fading only one channel gets affected.
• It is used for analog signals.
• A large number of signals (channels) can be transmitted simultaneously.

Disadvantages:

There are some disadvantages of frequency division multiplexing (FDM) which are given below,

• It is suffers problem of cross-talk.
• It is used only when a few low speed channels are desired.
• Intermodulation distortion takes place.

Applications:

• It is used to public telephones and in cable TV systems.
• It is used in broad casting.
• It is used in AM and FM broadcasting.
