11: The future of digital scales and balances
As with any other attempt at prediction, determining the future of digital scales and balances is a risky proposition. What seems like the next big thing could turn out to be a flash in the pan, and the real future sneaks in when you weren’t expecting it. But let’s try anyway, shall we? First of all, let’s take a gander at the two most prominent methods technology of balance calibration: the strain gage load cell and magnetic force restoration....
12: Pulse Code Modulation In Satellite Radio
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...
13: Ionosphere Effect On Satellite Radio Waves
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 vibrating electrons collide with gas molecules from time to time in spite of the low gas pressure in the ionosphere....
14: Fading In Satellite Radio
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 namely general fading or synchronous fading and selective fading....
15: Magnetic Field on Radio Waves
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 earth’s magnetic field at right angles to the velocity of the electron. ...
16: Satellite Radio Connection With Microwaves
The Microwaves are portion of the electromagnetic spectrum where the wavelength falls between about one millimeter and thirty centimeters. Microwave frequency bands extend from about one gigahertz to three hundred gigahertz and are useful for short range, high reliability radio and television links....
17: Satellite Radio And Normal Man
All of us have our favorite radio stations that we preset into our car radios and keep on flipping between them as we drive to and from work, on errands and around town. But at times we travel too far away from the station. In this case the signal breaks up and fades into static. ...
18: Repeaters Purpose
The functions performed by repeaters are amplification and frequency down conversion. Repeater amplifies signal from a low power level of the order of negative hundred decibels watt to an output power level of the order of ten decibel watts thus providing again of the order of hundred and ten decibel. ...
