Since the resonant circuit in Figure. (2) is a parallel type. From the equation in parallel resonance, we get. or. For the high end of the AM band, f0 = 1600 kHz, and the corresponding C is. For the low end of the AM band, f0 ...
WebFM Radio Waves. FM radio waves are also used for commercial radio transmission, but in the frequency range of 88 to 108 MHz. FM stands for frequency modulation, another method of carrying information.(See this figure.)Here a carrier wave having the basic frequency of the radio station, perhaps 105.1 MHz, is modulated in frequency by the …
The center frequencies of the FM channels are spaced in increments of 200 kHz. The frequency of 87.9 MHz, while technically part of TV channel 6 (82 to 88 MHz), is used by just two FM class-D stations in the United States. Portable radio tuners often tune down to 87.5 MHz, so that the same radios can be made and sold … See more The FM broadcast band is a range of radio frequencies used for FM broadcasting by radio stations. The range of frequencies used differs between different parts of the world.
