Abstract: This article analyzes the improved module based on Jerk system, and completes the circuital design for multi-scroll chaotic attractor. The simulation and circuits are used to prove the design experimentally. Compared with traditional modularized circuits, this circuit is much simpler and gets the results more precisely. One can change different chips or regulate the value of integrating resistor to observe the chaos, and change the frequency spectrum for practical applications.

Key words: chaotic phenomenon, Jerk system, improved circuit, hardware experiment
