Installing ceramic or porcelain tile is both an art and a science. Tile installers must know the composition of the tiles as well as how to lay them in place attractively. Besides the normal costs of labor and materials, a tile project's costs vary by the type of sub-flooring to be used as a foundation for the tile.
Three things can cause an EMI problem: A signal source creates some kind of noise, there is a transmission path for the noise, and/or there is a receiver sensitive enough to be distorted by the noise, as shown in Figure 1.
Basic Elements of EMI/RFI. This article provides designers with an understanding of EMI/RFI root causes. EMI/RFI is said to exist when unwanted voltages or currents are present so that they adversely affect the performance of an electrical device or electronic system. These voltages/currents can reach the victim circuit or device by conduction or by non-ionizing radiation.
