How to do frequency 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 .

How to modulate a signal in Matlab?

y = modulate( x , fc , fs ) modulates the real message signal x with a carrier frequency fc and sample rate fs . If x is a matrix, the modulated signal is computed independently for each column and stored in the corresponding column of y . [ y , t ] = modulate( x , fc , fs ) also returns the internal time vector t .

What is frequency modulation formula?

The mathematical equation of frequency modulation

The frequency modulation equation includes: v = A sin [ wct + (Δf / fm) sin wmt ] Here, A is the amplitude of frequency modulation signals. ∆f is the frequency deviation.

What is amplitude modulation in Matlab?

Amplitude modulation (AM) is a linear baseband modulation technique in which the message modulates the amplitude of a constant frequency signal.
