Hi all!
I wonder if there's any better solution to my problem:
I have several sweep signals that excite a structure so I can identify its natural frequency. As the environment where the signal have been acquired its quite noisy I decided to filter both signals (excitation and response) with a dynamic filter which is moving with the sweep. The crosspectrum gave me better results but it still must be improved. Any idea? Maybe it would be better to use wavelets or any joint time frequency vi?
Thanks in advance mates
