Boundedness If 1 < p < ∞, then the Hilbert transform on $${\displaystyle L^{p}(\mathbb {R} )}$$ is a bounded linear operator, meaning that there exists a constant Cp such that for all $${\displaystyle u\in L^{p}(\mathbb {R} )}$$. The best constant $${\displaystyle C_{p}}$$ is given by An easy way to find … See more In mathematics and signal processing, the Hilbert transform is a specific singular integral that takes a function, u(t) of a real variable and produces another function of a real variable H(u)(t). The Hilbert transform is given … See more The Hilbert transform is a multiplier operator. The multiplier of H is σH(ω) = −i sgn(ω), where sgn is the signum function. Therefore: where $${\displaystyle {\mathcal {F}}}$$ denotes the Fourier transform. Since sgn(x) = sgn(2πx), it … See more It is by no means obvious that the Hilbert transform is well-defined at all, as the improper integral defining it must converge in a … See more The Hilbert transform of u can be thought of as the convolution of u(t) with the function h(t) = 1/ π t, known as the Cauchy kernel. Because 1⁄t is not integrable across t = 0, the integral … See more The Hilbert transform arose in Hilbert's 1905 work on a problem Riemann posed concerning analytic functions, which has come to be known as the Riemann–Hilbert problem. Hilbert's work was mainly concerned with the Hilbert transform for functions defined on … See more In the following table, the frequency parameter $${\displaystyle \omega }$$ is real. Notes See more Hilbert transform of distributions It is further possible to extend the Hilbert transform to certain spaces of distributions (Pandey 1996, Chapter 3). Since the Hilbert transform commutes with differentiation, and is a bounded operator on L , H … See more Webthat will motivate the de nition of the Hilbert transform. Then we de ne the Hilbert transform on the real line and study some of its main proper-ties. Among the properties we will see how it relates to the Fourier transform and show that it is an isometry from L2(R) to L2(R). To close this text we nally study the Hilbert transform on the unit ...
