| Abstract: | On the basis of hardware experimental research, a loop Chua's circuit is established, and its working principles as well as characteristics are introduced. A scheme for speech and music secure communication based onchaotic feedback modulation is presented. The principle of synchronization is analyzed. The synchronous convergence of circuits parameters matching between transmitter and receiver is discussed. Hardware experimental circuits are designed.Chaotic communication on speech and music signals transmission is demonstrated.Experimental results are given |
