1. Continuous linear decompositions
1.1 Fourier with sliding window
To carry out a local spectral analysis of a signal around an arbitrary time , we need to calculate a Fourier transform (FT) of the immediate vicinity of this point. Since the Fourier integral requires an infinite integration time, this implies that the local aspect is introduced by looking at the signal only within a certain interval T close to
