This method dates back to the 1870s, i.e., the time when we first discovered that information in the form of audio production can be broadcast over long distances through radio waves. Frequency Modulation, often referred to as FM, is another relatively newer method of modulation where the carrier wave is modified proportionally according to the input signal. In FM, the instantaneous frequency of the carrier wave is altered according to the amplitude of the input signal. AM involves the alteration of the amplitude of the carrier wave, whereas FM involves changes in the frequency of the carrier wave. The typical frequency range in which AM works is 535 to 1705 Kilohertz, whereas the frequency range is around 88-108 Megahertz for FM.\n
