"WebThe Hilbert transform was first introduced by David Hilbert in this setting, to solve a special case of the Riemann–Hilbert problem for analytic functions. In mathematics and signal processing, the Hilbert transform is a specific singular integral that takes a function, u of a real variable and produces another function of a real variable H .
