CHAPTER 7 MASS MEDIA I n Pakistan‚ the availability of mass media falls much short of international standards. For example‚ i n Pakistan 1.8 copies of newspapers‚ 2.9 radio sets‚ 0.6 T.V. sets and C. 5 cinema seats were available for every 100 persons as compared to the UNESCO suggeeion of 10 newspapers‚ 5 radio sets‚ 2 T.V. sets and 2 cinema seats for 100 persons. The facilities in Pakistan in this area as i n other social sectors are lower than the average for South-East Asia Region. This

chapter 3 Amplitude Modulation Fundamentals n the modulation process‚ the baseband voice‚ video‚ or digital signal modifies another‚ higher-frequency signal called the carrier‚ which is usually a sine wave. A sine wave carrier can be modified by the intelligence signal through amplitude modulation‚ frequency modulation‚ or phase modulation. The focus of this chapter is amplitude modulation (AM). I Carrier Amplitude modulation (AM) Objectives After completing this chapter‚ you

Before beginning our research on radio waves‚ to us‚ radio waves were just waves going through the atmosphere‚ carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves‚ and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves‚ which represent voice and other

reasoning behind how this could produce a signal. We know that electromagnetic radiation is produced by accelerating charges. In the radio transmitter‚ electrons oscillate up and down and are thus accelerating. An electron will exert a force on another electron when they are some distance away‚ like charges repel. When the electron in the transmitter oscillates up and down‚ the direction of the force it exerts changes since the source of the force is moving. It takes some time for the change

While the player uses the Wii Remote‚ the Wii game console determines the remote’s location by calculating the distance and angle between the Wii Remote and two transmitters on the sensor bar.
