Also, discrete wavelet bases may be considered in the context of other forms of the uncertainty principle.
A wavelet without compact support such as the Shannon wavelet would require O(N 2 ).
A wavelet -based approximate FFT by Guo and Burrus (1996) takes sparse inputs/outputs (time/frequency localization) into account more efficiently than is possible with an exact FFT.
As with other wavelet transforms, a key advantage it has over Fourier transforms is temporal resolution: it captures both frequency and location information (location in time).
A wavelet is a wave -like oscillation with an amplitude that begins at zero, increases, and then decreases back to zero.
