I had a question as to how to find out the frequency spectrum of a data pattern. I know if I can do FFT on the data pattern I should be able to do this. Are there any freeware tools that could do this. I am more interested in knowing the frequency spectrum of SONET data.=20 Any input will be highly appreciated. Thanks in advance Bob __________________________________________________ Do You Yahoo!? Yahoo!
