Internet is flooded with video sharing sites. More and more people are joining these sites to share their video clips. It is fun, excitement and an art. Most people just like to watch and enjoy. Many ...
Vital frequency is the maximum frequency of the radio wave which is returned from a layer for normal incident. In case the frequency of the radio wave exceeds the critical frequency the influence of t...
In troposphere under normal conditions the air pressure water vapor pressure and temperature reduces with the increase of height above earth. As a result of this the refractive index also reduces with...
While the M curve has a negative slope the curvature of the ray is concave downward on a plane earth diagram and the true curvature of the rays is greater than the curvature of the earth. Hence rays w...
Pulse amplitude modulation, pulse width modulation and pulse position modulation form cases of analog pulse system. Pulse code modulation and delta modulation form cases of digital pulse modulation. P...
The radio waves traveling through the ionosphere possess kinetic energy. This kinetic energy is imparted to the free electrons. Thus these free electrons in the ionosphere are set to vibration. These ...
By fading of a radio signal we mean that incident wave change in the field strength of signal received from distant transmitter. The fading of signal may be put into the following two categories namel...
The earth’s magnetic field exerts a deflecting force on the moving electrons. This force on an electron is proportional to the product of instantaneous velocity of the electron and the component of ea...
