Abstract: 

The bifurcation analysis of periodic solutions and homoclynic structures in nonautonomous system of differential equations which models phase—locked loop (PLL) is carried out with the qualitative numerical method using computer modelling. The chao tization of dynamics of the system is investigated. The bifurcation diagrams on the parameter plane with regions corresponding to different qualitative dynamics are presented. The achieved results are interpreted applying to PLL.
