- conjectures 7y agoIn what sense?
- planteen 7y agoA wavelet naturally gives a spectrogram. The Fourier transform taken on a signal will give you only frequency content, but no idea in time where this frequency occurred. A wavelet naturally gives both time and frequency information. Of course, if you take the Fourier transform at discrete time intervals in blocks, you can also construct a spectrogram.
