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.
Often, the first test used to diagnose anemia is a complete blood count (CBC). The CBC measures many parts of your blood. This test checks your hemoglobin and hematocrit (hee-MAT-oh-crit) levels. Hemoglobin is an iron-rich protein in red blood cells that carries oxygen to the body. Hematocrit is a measure of how much space red blood cells take up in your blood. A low level of hemoglobin or hematocrit is a sign of anemia. The normal range of these levels varies in certain racial and ethnic populations.
1 Iron promotes normal red blood cell production. 2  Iron is a vital component of hemoglobin. 3  Hemoglobin is the protein that transports oxygen in the blood. 4  Iron plays a role in delivering oxygen to the cells, including muscle cells. 5  Iron plays a key role in energy metabolism.he body's normal supply of iron is maintained by the body itself; it adjusts and controls the amount it absorbs from the food we eat. 1  Every living cell contains iron. 2  Iron promotes normal red blood cell production. 3  Iron is a vital component of hemoglobin. 4  Hemoglobin is the protein that transports oxygen in the blood.
