fast folding algorithm

(FFA)
(algorithm to find the periods of periodic data)

The fast folding algorithm is an efficient algorithm to find periodicity in time series data through data folding. It applies a method somewhat like that of the fast Fourier transform. Among its uses is identification of pulsars from radio observations collected over time.
