FDM vs. 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.ummary: 1. FDM is a physical layer multiplexing technique, while FDMA is a data link layer access method. 2. Using FDM to allow multiple users to utilize the same bandwidth is called FDMA.
The MCV is a valuable tool in the initial classification of anemia and helps determine the. most cost effective strategy for evaluating the etiology of a patientâs anemia. For. example, the presence of microcytosis should lead to iron studies as part of the initial.
Iron studies are requested in two main situations; the investigation of the cause of anaemia and when iron excess is suspected. This term refers to the presence of too few red blood cells, which are needed to carry oxygen to the body. Many conditions can cause anaemia, but iron deficiency is one of the most common.
