Dear IFEFFIT members,
I'm a fresh graduate student majoring in chemical engineering. I began
to learn XAFS by myself one month ago. I bought and read the book
/XAFS for Everyone/ written by Dr. Calvin. I think I have got a clear
image of how EXAFS works. Recently, I am attracted bythe technique
called Wavelet Analysis from literatures. It seems pretty powerful to
correlate both temporal and frequency information, but something just
wentprobably beyond my current knowledge base. I understand that a
changeable window should be adapted to a make a trade-off between time
and frequency, but I don't understand the logic that good
time-resolution in high frequency is preferred while in low frequency
a good frequency-resolution is better. I would appreciate it very much
if you could answer my half-baked question and offer me with some
learning material.
Best regards
Xinyu
