Harmonic Wavelet For Wavelet transform

by

 

Computes the Harmonic wavelet and outputs in the form similar to other wavelets

File Information
Description

[out1,out3]=harmonic(LB,UB,N) computes the Harmonic Wavelet with the lower Bound as 'LB' Upper Bound as 'UB' and N being the number of points in the wavelet.

The outputs are similar to other wavelets already available with Matlab. SO, the function can be used universally

 if Option > 0, a Plot of the harmonic wavelet created will be made.
           <=0, No plot will be done.

The function basically is for computing Harmonic wavelet transform for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis.

Out1 gives the real part of the wavelet
Out2 gives the imaginary part of the wavelet

Example:
       h_h=harmonic(0,3,1024,1);
