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.


  • 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


  • 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

    Here's a few links we found on the subject:  http://sunsite.queensu.ca/rmc/network/lanproject/lansample/network_implementation.htm  http://www.scottsnetworkclass.com/basic/basicprt.html
