Study Notes
Multiplexing Techniques
- Frequency Division Multiplexing (FDM) is a multiplexing technique that allocates different frequency bands to different signals.
Demultiplexer
- A demultiplexer is a device that separates the multiplexed signals back into their original form, restoring them to their individual identity.
Multiplexing
- Multiplexing is the process of combining multiple signals or data streams into a single, high-capacity transmission medium.
Time Division Multiplexing
- Time Division Multiplexing (TDM) is a multiplexing technique that allocates time slots to different signals for transmission.
Multiplexer
- A multiplexer is a device that combines multiple signals into a single signal, allowing multiple data streams to share the same transmission medium.
