Fm vs Am
FM vs AM
FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.
FM signals have a great advantage over AM signals. Both signals are susceptible to slight changes in amplitude. With an AM broadcast, these changes result in static. With an FM broadcast, slight changes in amplitude don't matter -- since the audio signal is conveyed through changes in frequency, the FM receiver can just ignore changes in amplitude. The result: no static at all.
PHARAPHRASE:
AM radio works the same ways as FM radio works. How the carrier wave is modulates or altered is their difference. AM radio can be describe by its overall strength of the signal is varied to incorporate the sound information, while in FM radio the thing that varied is the frequency of the carried signal.
FM signals is better than the AM signals. Bothe signals are influenced to slight change in amplitude. Static is the result with AM broadcast while the slight changes in amplitude in FM broadcasting doesn’t matter. Because of radio frequency the audio signal had been know, the changes in amplitude can be just ignore by the FM receiver and the result is no static at all.
Radio Communication. History of radio – Definition
In St. Louis, Missouri, Nikola Tesla made the first public demonstration of radio communication in 1893. Addressing the Franklin Institute in Philadelphia and the National Electric Light Association, he described and demonstrated in detail the principles of radio communication. The apparatus that he used contained all the elements that were incorporated into radio systems before the development of the vacuum tube.
In 1895, Guglielmo Marconi sent a telegraph
