Re: Broadband v. baseband ... again?

If you want to get to the root of these terms, without getting caught up 
in all of the ways their meaning has been distorted, the best place to look
may be a dictionary. 

In baseband signalling, you have one signal using all of the bandwidth
available on the wire.  In broadband signalling, there are multiple signals
on the wire, multiplexed in the frequency domain.
