3 unusual facts about Hilbert transform


Halbach array

The mathematical transform which shifts the phase of all components of some function by \scriptstyle\frac{\pi}{2} is called a Hilbert transform; the components of the magnetization vector can therefore be any Hilbert transform pair (the simplest of which is simply \scriptstyle\sin

Hilbert transform

The Hilbert transform is named after David Hilbert, who first introduced the operator in order to solve a special case of the Riemann–Hilbert problem for holomorphic functions.

Two-dimensional correlation analysis

Because of its computational efficiency and simplicity, the Hilbert transform is nowadays used for the calculation of the 2D spectra.
