Might want to check these. http://mathematica.stackexchange.com/questions/5852/how-to-find-the-period-of-an-arbitrary-mathematical-function http://mathematica.stackexchange.com/questions/38217/finding-fourier-transform-of-data-and-hence-frequencies http://mathematica.stackexchange.com/questions/42783/how-do-you-find-the-frequency-and-amplitude-from-fourier/43006#43006 Daniel Lichtblau Wolfram Research ------------------ By selecting maxima/minima or otherwise, is there a way to find time period of a function defined/available numerically? In maths basically, are there criteria governing structuring of differential equations that generate periodic functions? Narasimham
