Difference between FM and AM
The differences between FM and AM can easily learnt form the table added below,
Amplitude Modulation vs Frequency Modulation |
|
---|---|
AM(Ampltude Modulation) |
FM(Frequency Modulation) |
AM has a bad sound quality as compared to FM | FM has a good sound quality as compared to AM |
It is cheaper | It is expensive |
AM can be sent over a large distance | FM can be blocked by things like walls |
Less power efficient | More power efficient |
Shorter broadcast range | Longer broadcast range |
Modulates amplitude of the carrier signal | Modulates frequency of carrier signal |
Demodulation is relatively straightforward | Demodulation is more complex than AM |

Frequency Modulation
Frequency Modulation or FM is a method of encoding information on one carrier wave by changing the wave carrier frequency. Frequency Modulation technology is used in the fields of computing, telecommunications, and signal processing. In frequency modulation, the frequency of the carrier wave is changed according to the frequency of the modulating signal.
In this article, we will discuss the definition of frequency modulation, its advantages and disadvantages, the modulation index, the differences between AM and FM, and the expressions for frequency modulation.
