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
