Finding periodic signals

 

tex2html_wrap_inline3922   Fourier analysis
tex2html_wrap_inline3922   But these are not sinusoidal signals!
tex2html_wrap_inline3922   Signal strength is spread over several harmonics
tex2html_wrap_inline3922   Harmonic folds (incoherent)
tex2html_wrap_inline3922   Coherent fold search on small grid
tex2html_wrap_inline3922   Also have to search in DM
tex2html_wrap_inline3922   Account for size of search space when assessing significance of any spikes in the spectrum
tex2html_wrap_inline3922   Significance tex2html_wrap_inline4194
