Q. Commercial FM radio broadcasting?

Commercial FM radio broadcasting utilizes the frequency band of 88 to 108 MHz for the transmission ofmusic and voice signals. The carrier frequencies are separated by 200 kHz, and the peak frequency deviation is fixed at 75 kHz. Each station (out of the possible 100) broadcasts in a channel bandwidth of 200 kHz centered on the carrier. The FM system is capable of presenting higher quality audio to the user than AM because of the larger audio band allowed from 50 Hz to 15 kHz. Distortion at most stations is below 1%. Besides broadcast applications, FM is also used in satellite links, aircraft altimetry, radars, amateur radio, and various two-way radio applications. Because of the larger bandwidth (up to 20 times more than in AM), an FM system has more freedom from interference and better performance in noise than any AM station.
