low power fm antenna

In amplitude modulation, the sidebands contain the signal. The power in the sidebands is the only useful power. The power carrier by the side bands is only 33.3% even when there is 100% modulation. If modulation is 50%, then power carried by the sidebands is..

The demand for electricity varies at different times of a year. One big disadvantage is that the wind, waves and tides do not occur at all time and hence cannot guarantee steady production of electricity. Hydroelectric power stations can solve this problem. When the demand is l..

. A good quality service can be continuously ensured by a global operational satellite system. Thus, communication satellites would give a valuable service in addition to the submarine cable and high frequency radio systems. Geostationary communication satellites have enabled not only national but ..

Electric power is usually generated at places which are far from the places where it is consumed. Distribution of Electricity from Grid The power is transmitted over long distances at high voltage to minimize the loss of energy during transmission. For a given electric powe..

Low density and strength make it ideal for construction of aircraft, lightweight vehicles, and ladders. An alloy of aluminium called duralumin is often used instead of pure aluminium because of its improved properties. Easy shaping and corrosion resistance make it a good material ..

. This is made up by energy diffracted down- ward from the upper portions of the wavefront. There is another way in which the surface wave is attenuated. Because of diffraction, the wavefront gradually tilts over, as shown in the below figure. As the wave propagates over the Earth, it tilts over mo..

Advantages of Using Solar Energy - It is present everywhere. It is available in plenty. It does not cause any environmental pollution like the fossil fuels and nuclear power. Solar cells last a longer time and have low running costs. In the first half of the twentieth century solar e..
