Dear all,
Here is a conversation long time ago on the necessity of removing linear trend before filtering, if we think linear trend is a kind of noise. Hope this information is helpful for some of us!
P.S., whether linear trend is meaningful or not, @WANG Xin-Di is going to have a nice work on that issue. Hopefully we can have it published in the near future.
Signal:
y=sin(4*2*pi*t)+sin(2*2*pi*t)+
