Effect of data gaps: comparison of different spectral analysis methods
In this paper we investigate quantitatively the effect of data gaps for four methods of estimating the amplitude spectrum of a time series: fast Fourier transform (FFT), discrete Fourier transform (DFT), <i>Z</i> transform (ZTR) and the Lomb–Scargle algorithm (LST). We devise two test...
