Hi,
I understand that you are seeking assistance with spectral whitening, identifying spectral peaks, and finding the corresponding frequencies in MATLAB.
To spectrally whiten a signal, you can use the MATLAB function "Spectral whitening" available on the MATLAB File Exchange. The link is provided below. This function generates a flat Fourier spectrum for a non-white signal, either across the full frequency range or within a user-defined frequency band.
The output "xnew" represents the spectrally whitened signal, which spans the entire frequency range from 0 Hz to the "Nyquist frequency".
To find spectral peaks in a signal, you can utilize the "findpeaks" function in MATLAB. This function identifies local maxima in the signal, which correspond to the peaks. To access the documentation for the "findpeaks" function, you can follow the link provided below.
To determine the locations of the peaks in the signal, you can refer to the "Find Peaks and Their Locations" section within the documentation of the "findpeaks" function.
If you encounter difficulties in determining the frequencies associated with the peaks, you can refer to the below link which offers insights and solutions on how to find specific frequencies in a signal.
