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.
The biggest differences between the two tube types are: 1) The buffer tube diameter itself 2) The diameter of the threads in relation to the diameter of the tube. Mil-Spec: On the mil-spec buffer tubeâ¦ the threads at the front are actually a larger diameter than the rest of the tube itself. In manufacturing, a large tube is used and threads lathed as normal. Next, the rest of the tube must be milled down to the military specified diameter.
