Hi I have question ?. I have a curve say input f(t) which is function of time t and this is harmonic.From this input agter processing i get output say g(t) which is periodic and funation of time. When I plot above function in time space.I find same pahse difference between and also there is difference in magnitude. I want to how to compute this phase difference.I know it has something to do with FFT. So anybody who has already done it before and knows of some reference pls reply. Thanks in advance. prasat

None has asnwers for it?This I think is a very easy question?May be everybody is thinking that it is too simple too answer it? What is the problem let somebody specify it? Thanks pratap
