| Abstract: | Three methods for calculating the periodograms of superimposed epochs, designed for revealing and investigating periodic components
with nonharmonic signal forms are described. Examples of periodograms and Fourier spectra calculated for model time series
with known properties are presented. Comparative efficiency of the methods for signals of different forms is discussed. The
results of analysis of different experimental signals will be compared in a separate paper that will be a sequel to this work
on the optimized choice of methods for analysis of periodic processes. |
