Answer Posted / visakh
In TDM, different users share the same channel based on
time slots alloted to them. Each user or source is given a
particular time slot to send its information.
Advantages:
1. The entire channel BW is available for a particular time
interval unlike in FDM where the channel BW is split into
smaller segments. This enables higher data rates.
2. All users share the same frequency, so spectrum
efficieny is increased. Available channel BW is no more a
constraint.
3. TDM is very useful since it takes advantage of the
bursty nature of voice signals. Voice data is not
continuous, it happens in bursts. Other users transmit data
during the slots of silence using TDM.
