You should widen your scope by looking a "time series" instead of harmonic
analysis. There is a task view on the subject at

My thoughts exactly.

?FFT should do the job.

And define the dominant term - a_n**2 + b_n**2 - the Parseval Relation.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.

Do you need time localization, or are you only interested in the
period of the high frequency?  If you do need time localization why
not use a CWT to look at the signal?
