Hi Tom,
As hilbert transform is a high-pass filter which only allows the
positive frequency components.And we know that only a complex signal
can have a single sided spectrum,not a real signal.So, i am still
confused that why the signal isn't showing any imaginary part??May b i
am not understanding
Thanx Marcus and Tom fr ur explanations. I will read further and ask any
questions if i have.

Hi Ali,
I see an imaginary part whenever the real part drops from 1 to 0; which
is to be expected, since the Hilbert filter is a high pass one.
Background: Remember, this is the digital world. There is no Hilbert
transform here -- there could only be a discrete Hilbert transform. And
even that is
For those who do not read the excellent newsgroup comp.dsp, here is a link
