IMF for Bearing Fault Diagnosis
IMF_BEARING() does the Empirical Mode Decomposition of the signal 'y' of sampling frequency 'Fs'. 'l' mentions the lth imf, whose FFT plot will be plotted. The function returns the IMFs and the FFTs of all the IMFs.
The function basically is for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis.
The function plots all the IMF in one single plot and also plots the FFTs of the IMF mentioned by l.
Example:
[y,Fs] = wavread('Hum.wav');
l=2;
imf_bearing(y(1:10000),Fs,l);
