Chaotic behaviour of state variable filters with saturation-type integrators

Abstract

This brief paper describes possibility to see route-to-chaos scenarios in common analogue filtering structures known as the state variable filters. It is shown that strange attractors characterized by a fractal geometrical dimension can be observed in these naturally linear network structures if integrators are supposed to be exclusive nonlinear two-ports.This brief paper describes possibility to see route-to-chaos scenarios in common analogue filtering structures known as the state variable filters.
