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. Because 1⁄t is not integrable across t = 0, the integral defining the convolution does not always converge. Instead, the Hilbert transform is … 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.
