How do you find the fundamental frequency of a signal in MATLAB?

Use fft(). Then use the second return argument of max() to find the index of the highest signal. That's your fundamental frequency's index.

How do you find the frequency of FFT in MATLAB?

Y = fft(y,NFFT)/Datapoints; fs=Datapoints/Length; f = fs/2*linspace(0,1,NFFT/2+1);

How do you find the fundamental frequency of a Fourier transform?

The Fourier transform analyses the frequency content of a signal by decomposing it into sinusoids at different frequencies. A signal with a period T repeats at a rate of f₀ = 1/T, which is referred to as the fundamental frequency of the signal.

How do you find the frequency vector in FFT?

In many examples including the documentation about fft, the one-sided frequency vector is defined as: f = Fs*(0:(L/2))/L where L=length of the FFT.
