Hilbert ignores imaginary part of input
WebMar 6, 2016 · It is designed for real-valued input sequences and it will ignore any imaginary part. Note that despite its name this function does not simply return the Hilbert transform … Webthe names of the arrays, Re X [k ] becomes the real part of the complex frequency spectrum, and Im X [k ] becomes the imaginary part. In other words, we place a j with each value in the imaginary part, and add the result to the real part. However, do not make the mistake of thinking that this is the "complex DFT."
