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.
Serum iron, total iron-binding capacity (TIBC) , and/or transferrin tests are usually ordered together and, subsequantly, the transferrin saturation can be determined and used to assess how much iron is being carried in the blood. A ferritin test may also be used to evaluate a person's current iron stores.hese tests are used together to detect and help diagnose iron deficiency or iron overload. In people with anemia, these tests can help determine whether the condition is due to iron deficiency or another cause, such as chronic blood loss or some other illness.
