Abstract Delayed dynamic systems present very rich behaviours and play a primordial role in technical and industrial applications, such as cryptography and data security in telecommunications. In this work, the design and realisation of hybrid analog–digital circuits are done based on hybrid circuits. The digital part of this hybrid circuit is essentially constituted by the microcontroller, which makes it possible to create the delay in the systems considered and the remainder of the circuit is constituted by analog components (passive and active). The communication between the analog and the digital part is effective through the digital-to-analog converter (DAC) and analog-to-digital converter (ADC). Implementation of this new hybrid circuit makes it possible to reproduce the behaviours obtained by the digital simulation. Ausführliche Beschreibung
