[comp.dsp] Phase unwrapping

scott@figment.disney.com (Scott Watson) (03/21/91)

Dear group mind,

Do any of you have any software that does phase unwrapping in the
fourier domain? Or could you point me to an archive site??

I'll summarize to the net.

Thanks in advance,

Scott - Here is some potentially useless info. In early 1988, I read a paper
by Bednar and Watt, presenting a fast algorithm for phase unwrapping. I don't
remember which domain; heck, I don't even remember the publication. It was 
some IEEE pub, probably the trans on ASSP, printed between 1985 and 1988.
Hope you can find an index! Maybe some diligent, magazine-saving netter
can help. Good Luck.
