Experimental study of high frequency stochastic resonance in Chua circuits
We study the stochastic resonance phenomenon occurring in electronic Chua circuits operating in the chaotic regime when the forcing signal is modulated at relatively high frequency, of the order of magnitude of the main Chua frequency in the absence of forcing (fo). In all the cases, a clear maximum in the signal-to-noise ratio for an intermediate noise level is observed. When modulating with a...
متن کاملChua Circuits
Chua circuits are the simplest circuit that meets the requirements to exhibit chaotic behavior and are cheap to construct with plenty of background research to check the accuracy of our results with. The initial design of the experiment was to synchronize multiple chaotic chua circuits acoustically to investigate ways of data masking for secure information transfer. This did not work out, and t...
متن کاملExperimental characterization of stochastic resonance in coupled chaotic circuits
Stochastic Resonance is a phenomenon observed in nonlinear systems whereby an input signal is optimized due to the beneficial effect of noise. This phenomenon has been observed in many real-world systems[1] including lasers, chemical reactions and biological systems and has many potential applications. This report will focus on the phenomenon of phase synchronization in coupled chaotic systems ...

چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
15 صفحه اولHigh Frequency Stochastic Resonance in Periodically Driven Systems
High frequency stochastic resonance (SR) phenomena, associated with fluctuational transitions between coexisting periodic attractors, have been investigated experimentally in an electronic model of a single-well Duffing oscillator bistable in a nearly resonant field of frequency ωF . It is shown that, with increasing noise intensity, the signal/noise ratio (SNR) for a signal due to a weak trial...
