Talk:Communication Systems/Frequency-Division Multiplexing

how all frequency carriers of signals get carried through a coaxial cable?


 * Magic! The answer is frequency division multiplexing (FDM) where each carrier is a different frequency, and all the frequencies are added together into the spectrum. At the receiving end, a series of filters can separate each carrier out from the spectrum, frequency shift it back to DC, and reconstructs it into the transmitted signal. --Whiteknight (Page) (Talk) 20:27, 19 September 2008 (UTC)
