The Hilbert transform has many uses, including solving problems in aerodynamics, condensed matter physics, optics, fluids, and engineering. Written in a style that will suit a wide audience (including the physical sciences), this book will become the reference of choice on the topic, whatever the subject background of the reader.

Publisher Summary This chapter focuses on a generalized way of treating narrow-banded processes from mathematical and physical points of view using the Hilbert transform. The methods described are not limited to narrow-banded processes but work perfectly well for broad-banded spectra as well. When working with theoretical or experimental wave trains,

Hilbert-Transformation (HT) [PDF]
, 1985 In Aufgabe A7.1 wird die HT im Zeitbereich angewendet, auserdem wird der „Hilbert-Transformator“ eingefuhrt, dessen Impuls- und Sprungantwort in weiteren Aufgaben dieses Kapitels Anwendung findet. Die HT im Frequenzbereich verbindet Real- und Imaginarteil der Ubertragungsfunktion eines realisierbaren Systems. Dies wird in 7.2 naher untersucht.

On the bilinear Hilbert transform
1998The author and \textit{C. Thiele} in their highly acclaimed paper ``On Calderón's conjecture'' [Ann. Math. (2) 149, No. 2, 475-496 (1999; Zbl 0934.42012)] have proved that the bilinear Hilbert transform \[ Hfg(x):= \lim_{\varepsilon \rightarrow 0}\int_{|y|>\varepsilon}{f(x+y)g(x-y) {\frac{dy}{y}}} \] extends to a bounded operator on \(L^p\times L^p ...

In diesem Kapitel wollen wir uns mit einer Transformation befassen, die in der Modulationstheorie eine grose Rolle spielt: durch geeignete Erganzung des ursprunglichen Signals x(t) zu einem sogenannten analytischen Signal z(t) = x(t) – jy(t) erhalt man eine komplexe Zeitfunktion mit einseitigem Spektrum. Dies geschieht dadurch, das man y(t) als Hilbert-
