TDM | FDM |
---|---|
The signals which are to be multiplexed can occupy the entire bandwidth but are isolated in the time domain | Signals which are to be multiplexed are added in the time domain. But they occupy diff slots in the frequency. domain |
TDM is preferred for the digital signals. | FDM is usually preferred for the analog signals. |
Synchronization required | Synchronization not required |
TDM circuiting is not very complex. | The FDM requires a complex circuiting at the transmitter and receiver. |
In TDM the problem of crosstalk is not severe. | FDM suffers from the problem of crosstalk due to imperfect band filters. |
Due to fading only a few TDM channels will be affected | Due to wideband fading in transmission medium, all FDM channels are affected |
Due to slow narrow band fading all the TDM channels may get wiped out. | Due to slow narrowband fading taking place in the transmission channel only a single channel may be affected in FDM |
