New discrete displays of classical self-oscillatory systems - Van der Paul and Rayleigh’s oscillators are offered. Displays with the kept temporary characteristics of response of linear system on external influence are received on the basis of combination of methods of parametrical synthesis and invariancy of pulse char- acteristics of dynamic systems. Examples of generation of regular and chaotic self-oscillations in discrete time are given. For the analysis of self-oscillations in the received discrete systems the method of slowly changing amplitudes is used. The effect of substitution of frequencies in a range of self-oscillations with use of the improved first approach is considered.

The results of numerical simulation of self-oscillations in a two-stage ring oscillator with active cells of Van der Pol are presented. It is shown that for large exceedances of generation threshold in a system with identical cells, non-uniform spatial distribution of amplitudes of self-oscillations is observed.
