All FM radio stations transmit in a band of frequencies between … WebIn the case of an FM receiver the RF is much higher frequency so an IF of 10.7MHz is normally used. An AM/FM receiver has both 455KHz and 10.7KHz tuned circuits in its IF stages, allowing it to work equally well for both bands. In fact, if you mix two frequencies f1 and f2, you get not only f1 - f2 but also f1 + f2.

WebHowever an AM radio may detect the sound of an FM broadcast by the phenomenon of slope detection which occurs when the radio is tuned slightly above or below the nominal broadcast frequency. Frequency variation on one sloping side of the radio tuning curve gives the amplified signal a corresponding local amplitude variation, to which the AM … WebAM (or Amplitude Modulation) and FM (or Frequency Modulation) are ways of broadcasting radio signals.
