fast folding algorithm

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

The fast folding algorithm is an algorithm analogous to the fast Fourier transform to efficiently find periodicity in time series data through data folding. Among its uses is identification of pulsars from radio observations collected over time.
