Which function is used for frequency modulation?
Sinusoidal baseband signal
The harmonic distribution of a sine wave carrier modulated by such a sinusoidal signal can be represented with Bessel functions; this provides the basis for a mathematical understanding of frequency modulation in the frequency domain.
How FM signal is generated?
FM signals can be generated either by using direct frequency modulation, which is achieved by inputting a message directly into a voltage-controlled oscillator, or by using indirect frequency modulation, which is achieved by integrating a message signal to generate a phase-modulated signal, which is then used to ...
How to do FM modulation in Matlab?
y = fmmod( x , Fc , Fs , freqdev ) returns a frequency modulated (FM) signal y , given the input message signal x , where the carrier signal has frequency Fc and sampling rate Fs . freqdev is the frequency deviation of the modulated signal. The value of Fs must satisfy Fs ≥ 2 Fc .
