In order to generate complex chaotic attractors

a new four-dimensional chaotic system is built in this paper

which gives birth to a true four-winged chaotic attractor

graph in time domain and power spectrum were drawn

electronic circuit was designed to realize the chaotic system.Experimental chaotic behaviors of the system were found to be identical to the simulations

and it is easy to realize in circuit.The circuit is important to secure communication and practical applications in communication encryption.
