Modulation Index
Modulation index is denoted by μ. It is the ratio of the amplitude of modulating signal to that of the carrier signal.
μ = Am/ Ac
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.
