90 degrees phase shifter - palm...@hotmail.com - Nov 26 17:00:18 2009

Hi,
I need to make a 90Âº phase shifter for a digital crossover audio system.
I've heard something about Hilbert Transform but I would like to know if it is
the best way to do a phase correction.
Does anybody know if I can implement a 90Âº phase shifting with cascade IIR
biquad sections?

Thanks in advence
