WebSep 16, 2015 · One application of the Hilbert Transform is to obtain a so-called Analytic Signal. For signal s ( t), its Hilbert Transform s ^ ( t) is defined as a composition: s A ( t) = s ( t) + j s ^ ( t) The Analytic Signal that we obtain is complex valued, therefore we can express it in exponential notation: WebJan 17, 2024 · An integer vector of Hilbert indices, or when attach is TRUE, the original object (data.frame or matrix) with a new integer column (h for data.frame) containing the Hilbert indices.
