WebHere are the key components of the two satellite radio systems: Satellites. Ground repeaters. Radio receivers. Satellite radio works a lot like satellite TV -- you purchase a receiver and pay a monthly subscription fee for a certain number of channels. For the moment, there are slight variances in the three satellite radio companies' systems. AM stands for Amplitude Modulation, and FM stands for Frequency Modulation. Both AM and FM radio programs are transmitted over the air via radio waves, which are part of a range of electromagnetic waves that include gamma rays, x-rays, ultraviolet rays, visible light, infrared, and microwave. Electromagnetic waves … Ver mais Electricity in the air is random noise. To be turned into useful signals that transmit information (music or voice), electricity must first be modulated. Therefore, modulation is the basis for AM and FM radio signals. Another … Ver mais AM radio uses amplitude modulation, the simplest radio broadcast form.
