Me too. > > Broadband specifically refers to dual-purposing the line for some other > kind of transmission for networking purposes. ie, it takes its name from In the old days, broadband meant signal transmission over a broader spectrum of frequencies -- baseband meant signal transmission using one base frequency, i.e. 10BaseT meant 10 MHz(Mbits/s) baseband over Twisted pair. Anyone who has worked with hardware knows that the two require quiet different circuitry -- these days, no one cares about hardware any more. Following the old definition, the classic 4 kHz phone line would be broadband, as would be a GHz TV cable with 'analog' TV and 'digital internet' bands next to each other. Broadband allows you to carve out a spectral range (band) as needed -- baseband does it through multiplexing (switches or collision control) So what do learn students these days about broadband vs. baseband ?
