WebWe would like to show you a description here but the site won’t allow us. The Hilbert transform is important in signal processing, where it is a component of the analytic representation of a real-valued signal u(t). The Hilbert transform was first introduced by David Hilbert in this setting, to solve a special case of the Riemann–Hilbert problem for analytic functions. 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 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 $${\displaystyle u\in L^{p}(\mathbb {R} )}$$ 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. … 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 1. ^ Some authors (e.g., Bracewell) use our −H as their definition of the forward transform. A … See more WebJan 13, 2003 · Corollaries include determination of the Gelfand–Kirillov dimension of any unitary highest weight representation occurring in a dual pair setting, and the determination of their Hilbert series (as a graded module for p −).
