Simultaneous amplitude and Frequency Noise Analysis in Chua's Circuit
نویسندگان
چکیده
A large number of simultaneous frequency and amplitude data from an electronic chaotic circuit (Chua’s circuit) have been obtained. These acquisitions are validated by plotting the bifurcation diagrams of the experimental data versus the bifurcation parameter. We introduce a topological parallel between the Colpitts oscillator and Chua’s circuit, and look for similar behavior of the frequency fluctuations using the Allan deviation.

متن کاملOpen-loop frequency response for a chaotic masking system
In this paper, a new numerical simulation approach is proposed for the study of open-loop frequency response of a chaotic masking system. Using Chua's circuit and the Lorenz system as illustrative examples, we have shown that one can employ chaos synchronization to separate the feedback network from a chaotic masking system, and then use numerical simulation to obtain the open-loop synchronizat...
متن کاملExperimental Evidence for vibrational resonance and Enhanced signal Transmission in Chua's Circuit
We consider a single Chua’s circuit and a system of a unidirectionally coupled n-Chua’s circuits driven by a biharmonic signal with two widely different frequencies ω and Ω, where Ω ω. We show experimental evidence for vibrational resonance in the single Chua’s circuit and undamped signal propagation of a low-frequency signal in the system of n-coupled Chua’s circuits where only the first circu...
متن کاملFrequency–driven chaos in the electrical circuit of Duffing-Holmes oscillator and its control
Accurate detection of weak periodic signals within noise and possibility of secure messaging have made Duffing oscillator (DO) highly important in the field of communication. Investigation on the properties of DO is thus ardently sought for. An elegant approach to accomplish the same is to fabricate electronic circuit simulating DO non-linear equation and to study the effect of input signal amp...
