Dear all,
I have tried to implement a Hilbert transformation with
GSL. This works quite fine with gsl_integration_qawc for
a given function in analytical form as numerator. But it
turns out, that the function can not be discrete (e.g.
as a sampled signal) due to the undelying bisection
algorithm.
Did anybody implement the Hilbert trafo with GSL for
discrete functions?
Thanks in advance for any hint.
Axel

Axel,
You may find an algorithm in the book by Stefan L. Hahn
entitled "Hilbert transforms in signal processing". See pages 58-59

Nils
