Electromagnetic Compatibility of Devices - Essay Example This paper illustrates that while engineers worked on a large number of devices and their functions in an environment of electromagnetic fields, but still there is the great need for research in this field to come up with substantial human and friendly devices.  The very common example is watching TV every day! If the text message or phone call in the dynamics that are attached to the computer and the TV sound. Prior research on EMC, a lot of cases, such as the sharpness of the speakers sound, noise and stop in alarm systems, distortions in telephone lines, violations of the equipment installed in hospitals, police, schools, and others have been identified. Such problems persist until the end of the twentieth century. Experts like describes the introduction of new products in the last decade of the twentieth century that were compatible with electromagnetic devices, but doubts have remained the same. The required bandwidth for devices for the production of radiation is very high su ch as cell phones (a big emitter), the wireless set of connections, Bluetooth connection and PDAs emit electromagnetic radiation in a wide scale. This is the reason that the number of sensitive locations, such as intensive care units in hospitals, military data, and numbers, etc, is to be free from electromagnetic radiation. As Weston articulates that the devices used to detect fire and smoke, and devices that emit electromagnetic radiation should be studied continuously. Standards and specifications of the system operation are determined in accordance with their work. He also said that as the technology of electromagnetic devices have given a helping hand to the deployment of fire and smoke detection systems. Reducing Electromagnetic Compatibility, EMC is the word used to detail how well the equipment or system can function in its electromagnetic environment without inserting Electromagnetic trouble that line with other electric supply to the atmosphere. Electronic equipment that c an run and convergence criteria are called EMC devices.

Coursework Example Higher interest rates mean that lenders in a particular economy are able to enjoy higher return, more that in countries where there are low interest rates. Further, high interest rates are able to attract foreign capital and lead to high exchange rates. The effects of high interest rates are solved if inflation in a particular country is slightly higher than in other countries. There are also cases whereby the impact of high interest rates can be mitigated through other factors that function to lower the currency (Madura, 1998: 14). Effective exchange rates are usually used to determine country’s currency value in relation to other strong currencies in the index. Some of the world’s currency indexes include the U.S dollar, Japanese Yea and the euro. These currencies are adjusted to lower the effects of inflation in some countries. In addition, effective exchange may also refer to the value consumers are likely to pay for an imported commodity. The price usually comprise s of any tariffs and other costs incurred as a result of the process of importation (Somanath, 2011: 220). 2. Inefficiencies in Exchange Rates and Arbitrage Profits Arbitrage profits are made when traders purchase and sell their assets so that they can take advantage of the difference in the price. In particular, arbitrage profits arise due to the exploitation of price differences and takes place in similar financial instruments. In addition, prices can be exploited on different markets as well as in different ways. Arbitrage profits arise due to the efforts geared towards ensuring that prices do not fall from fair value over long periods of time (Clark and Ghosh, 2004: 2). Further, arbitrage refers to the simultaneous buying and selling of a commodity or asset in different markets with the main aim of making profits from the difference in buying and selling prices. For example, the dollar price of a British pound may be 1.70 pounds in London but 1.40 pounds in Paris, a trader can b uy 1 pound in Paris then sell that pound in London and make some profit (0.3) per pound sold. If the trader buys 10 million pounds, 3000,000 pounds profit will be realized before any transaction costs, if any exist (Clark and Ghosh, 2004: 2). Arbitrage can be seen as an exploitation of the misalignment of market quotes. In a perfectly competitive market, the evident price differentials that lead to arbitrage profits cannot exist. In essence, arbitrage profit is as a result of market imperfection in which traders buy cheap and sell expensively. In foreign exchange markets, traders have the opportunity to buy and sell continuously. This takes place through the exchange of one currency for another and again for another currency, finally getting back to the original currency in the series of instantaneous transactions, and thus leading to profits (Clark and Ghosh, 2004: 2). 3. Problems of Making Payment in a Foreign Currency in the Future The demand of a foreign currency will certainly affect the price of products to be purchased from that country. Trader therefore, needs to know demand on foreign currencies. The cost of a product may be higher compared to domestic substitutes when the demand of a foreign currency is high. Further, the choice of foreign currency also depends on the investment opportunities available in the particular country and those available in the domestic market. A trader will demand a foreign currency if he or she can transact business cheaply. The demand of a
