Fast Algorithm forward Spectral Analyse of Erratic Sampled Data
Abstract
The Lomb-Scargle manner performs speckled analysis on inconsistent sampled data and is known to be a performance manner to found, and test the significance away, weak periodic signals. The methods has until been thought to be 'slow', requesting of order 10(2)N(2) operations to analyze N data points. We demonstrate that Rapid Fourier Convert (FFTs) can be used in a novel way to create the computation of command 10(2)N login N. Although its use of the FFT, the algorithm exists in no way same to conventional FFT periodogram investigation. Algorithms for Spectral Analysis of Irregularly Sampled Time Serial
