title: [Biomathematical procedure for quantitative oscillation analysis].
abstract: In the first part of the paper oscillating phenomena are discussed which one can observe on different levels in anorganic and organic systems. This discussion will be performed from physical, biorhythmic, control, and general system theoretical point of view. Especially biorhythmic phenomena are taken into account by the stated classification scheme. In the second part four numerical procedures for biomathematical analysis of biorhythmic oscillations are explained. The analysis is understood as determination of the number of harmonic suboscillations which set up the whole process, and calculating the values of frequency, amplitude, and phase of these suboscillations. To perform the mentioned four numerical procedures computer programs are available which are written in ALGOL.
