Advantages and disadvantages and applications of time division multiplexing (TDM)

Advantages:

There are some advantages of time division multiplexing which are given below,

• Time division multiplexing systems are more flexible than frequency division multiplexing.
• Time division multiplexing circuitry is not complex.
• Problem of cross talk is not severe.
• Full available channel bandwidth can be utilized for each channel.

Disadvantage:

There are some disadvantages of time division multiplexing which are given below,

• Synchronization is required in time division multiplexing.
• Complex to implement.
• Due to slow narrowband fading, all the TDM channels may get wiped out.

Applications:
