Difference Between FDM and FDMA. Frequency Division Multiplexing, or FDM, is a multiplexing technique for the physical layer that allows multiple low bandwidth signals to share the same high bandwidth frequency range. It is achieved by allocating a smaller frequency range to each signal that is using the same channel.
Complete setup for. the systems that use these technologies range from $9,900 to. over $600,000. There truly is something for everyone and every application; so. much so that many companies operate both FDM and PolyJet. machines to take advantage of each systemâs strength. However, for those with a budget that forces the selection of only one system, consider operations, part characteristics and material options.
