How do we estimate instantanious frequency of a signal using S-transform ? You don't. Instantaneous frequency shows you the dominant frequency at each...

Fourier transform is an isometric automorphism on S {\displaystyle S} . So to each ϕ ∈ S {\displaystyle \phi \in S} there is an associated ψ ∈ S {\displaystyle...

about the Constant Q transform, at least to see its essential definition. The section Constant_Q_transform#Calculation_of_the_Transform is already in trouble...

like the information contained in the article, but I find that Wavelet transform would be a more appropriate title for it. At least from the perspective...

two-sided Laplace transform is { B f } ( s ) = φ ( s ) = ∫ − ∞ ∞ e − s x f ( x ) d x {\displaystyle \left\{{\mathcal {B}}f\right\}(s)=\varphi (s)=\int _{-\infty...

right in front of you. How 'bout a formula or two? Perhaps the Fourier transform? User:Kevin_baas -2003.05.06 I didn't understand the part about the basis...

difference between ln s/s and ln s. (ln s)/s becomes very negative much faster than ln s as s goes to 0. And it is always true that ln s/s < ln s on the interval...

The article should say what the Hilbert transform is used for; currently is does not, and this is a significant omission. I suggest a section be added...

transform F(s) = s/(s2 + ω02) whose ROC is Re(s) > 0. As s = iω is a pole of F(s), substituting s = iω in F(s) does not yield the Fourier transform of...
