Baseband vs. broadband signalling
I am currently in my second year at university and am experiencing difficulty in finding suitable sites to answer the following question: "Sychronous systems use either baseband or broadband signalling. Explain each and contrast the differences." Any help or appropriate links to sites would be appreciated.
Here is a list that highlights the main differences between baseband and broadband signalling.
BASEBAND
- Uses digital signalling
- Bi-directional transmission
- No frequency-division multiplexing Signal travels over short distances - (attenuation becomes evident after 1 km of medium, after which repeaters can be used to retransmit the signal)
- Used primarily on bus
- Uses Manchester or differential Manchester encoding
BROADBAND
- Uses analog signalling
- Unidirectional transmission
- Frequency-division multiplexing is possible - Separate channels can support separate and independent data traffic)
- Signal can travel over long distances before being attenuated
- Good for both bus and tree topologies
- No digital encoding
