Return the Hilbert transform of a signal

This function is used to compute the Hilbert transform of a signal. It is based on function HilbertTransform() from (defunct) package hht, which was modified from the EMD package by Donghoh Kim and Hee-Seok Oh (http://dasan.sejong.ac.kr/~dhkim/software.emd.html)

Usage

hilbert_transform(x)

Arguments

x

The signal vector to be buffered

Value

The "analytic signal," in other words the Hilbert transform of the input signal x

Examples

timez <- seq(from = 0, by = 1/1024, to = 1)
x <- sin(2*pi*60*timez)
y <- hilbert_transform(x)
