Algorithms and programs are described which allow time series analysis
of periodic, multi-periodic, quasi-periodic, and aperiodic signals of an arbitrary
nature with equidistant and non-equidistant arguments. The methods are applied to
the observations of semiregular, dwarf nova, eclipsing, and Mira-type stars.
