Question about Fourier transformation in Matlab
Reply to thread
Message
[QUOTE="FactChecker, post: 5650774, member: 500115"] It sounds like you are removing the coefficients of the very periodicity that you expect it to have. Shouldn't those be the ones you keep? If you remove the period, you should expect noise. Is that what you expected? Is that what you got? PS. Before you go too far, I think you should apply some time series analysis like Box-Jenkins and see what autocorrelations are in the data. [/QUOTE]
