phase shift

Hi,
 
I am acquiring a analog signal, of about 500Hz, using LabView 7.0 and PCI-6221. Now, I need to shift this signal by 90 electrical degrees. How can I do this inside LabView?
 
Thank you,
Jeferson

A Hilbert Transform will shift it 90 degrees.

Randall,

A Hilbert Transform will give a 90 degrees lead, but I need a 90 degrees lag (time delay).

Do you have a hint?

 

Thanks

I am assuming that negating the result is not going to give you the right answer.  Then, you can try the inverse Hilbert Transform.
