This paper presents the design of the correspondi Hilbert … WebFeb 1, 2014 · These Hilbert-pairs are exactly orthogonal but are also almost symmetric. They therefore have the advantages found in both orthogonal and biorthogonal wavelets. Symmetry in the wavelets is of prime importance in many applications as it offers a better directional selectivity.
WebRiemann-Hilbert problems.1In other words, we are adopting a point of view according to which the Riemann-Hilbert (monodromy) problem is formally treated as a special case (although an extremely im-portant one) of aRiemann-Hilbert (factorization) problem. The latter is viewed as an analytic tool, but one whose implementation is not at all ...

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.
