The communication system needs to be protected from natural and man-made interference. Practical reference provides through an understanding of how to protect communication systems from electromagnetic interference, intentional and unintentional. This unique resource shows how to protect equipment from electric and magnetic fields, the design-TEM and GTEM Cells, build a capacitive coupling clamp for test sensitivity, protect electronic equipment with filters, and calculate the measurement uncertainty. This title contains time-saving software that helps engineers perform an important calculation, including the characteristic impedance of TEM-Cells, the cut-off frequency for higher order modes, and the cut-off frequency and resonance for the GTEM-cell.
