Synchronization of analog and discrete Rössler chaotic systems

In this paper synchronization of digital and analog Rössler chaotic systems is considered. The systems were implemented as an analog circuit and a numerical model. Three different cases were investigated: analog-to-analog, digital-to-digital and analog-to-digital synchronization. The digital model was obtained with semi-implicit numerical integration method giving fast and stable computer simulation. The possibility to synchronize coupled analog and digital systems was experimentally proven.
