"...I would like to express my thanks for making such a
wonderful tool for derivative spectroscopy, it has been much
help for me!
"...Interactive Fourier Filter is a great tool to help with
low-, high-, band-pass-, and band-stop filtering, and best of
all, you can view the effect of filtering parameters on your
time-series as you change them! "
" I have been using iSignal for the past day to analyze my data,
and it works GREAT!.... I am able to extract lots of information
from my spectra now."
