hi everyone,

i am using Short term fourior transform to analyse tennis racquet vibration. i have extracted the resonant frequecnies using accelerometers and i am calculating Q factors using the decay rate in m.s2. i would like to know if this method is A. valid and B. how can i get a bench mark test??

i have written a short 3 page papper describinbg the method of analysis so post you email and i can send.


thanks

Perhaps you can put it in the upload forum? Would be handy to be able to read what you are doing exactly.

The document has been placed in the upload section under the topic title:
