why wavelet transform is superior to STFT AND FT?
 

Wavelet can realize the spatial-frequency domain localization
I thinks there another many advantages about wavelet.
You can refer to some book on wavelet.
 

becoz of multiresolution propery.here time and frequency both scale r descritised.depending upon the application we can choose our wavelet to fulfill our criteria.funcionSTFT and FT fails in having this property.
 

This is dependent on apllications. But there is one difficullty when using wavelet: which do we can the good wavelet?
 

Simply put, the wavelet transform gives you frequency and time information as opposed to only refquency information given by the FT.
