Hello Michiel,
I see you tried to implement the Hilbert Transform.. DId you write this your self our did you try an example program? IBellow I put down a link to an example VI which does a Hilbert Transform. Did you see this VI before and does it also not do what you want to achief? The link:

Thank you for your reply. I indeed tried the example vi. However, i know found what i did wrong in initial testing. I took the square root of the signal before applying the Hilbert. Results are much better now. However, still one question: if I apply a signal that contains transients (say a sawtooth of 200 units in amplitude) the Hilbert results in a signal that has peaks up to 600 units. Is there any way compensate reliably for transients?
