We present experimental results on stabilizing unstable periodic orbits of an autonomous chaos oscillator based on a simple electronic circuit. Control is achieved by applying the difference between the actual and a delayed output signal of the oscillator. The quality of chaos control can be measured via the strength of perturbation. The dependence on the delay time shows a characteristic reson...

-In this paper a two dimensional chaotic modulator is proposed, based on an electronic controlled Colpitts Oscillator. The modulator is capable of producing constellations of distinct chaotic patterns in a bifurcation diagram, by creating pairs of specific characteristic values. Key-Words: Chaos, Colpitts Oscillator, Modulator, Voltage Controled Oscilator.

A class of RC-OTA hysteretic-chaotic oscillators has been previously reported using electronics; therefore, hysteresis is realized by an electronic circuit. To obtain a mathematical model of this RC-OTA chaotic-electronic device, hysteresis modeling turns an important issue. Here, we develop a new mathematical hysteretic model proposing a new jounce-chaotic oscillator. Chaosity test is proved u...

The aim of this tutorial is to provide an electronic engineer knowledge and insight for a better understanding of the mechanisms behind the behaviour of electronic oscillators. A linear oscillator is a mathematical fiction which can only be used as a starting point for the design of a real oscillator based on the Barkhausen criteria. Statements in textbooks and papers saying that the nonlineari...

It uses fluidic paths in feedback. Oscillator samples have been made using different technologies and materials. Micromechanical shaping...

A general form for ladder operators is used to construct a method to solve bound-state Schrödinger equations. The characteristics of supersymmetry and shape invariance of the system are the start point of the approach. To show the elegance and the utility of the method we use it to obtain energy spectra and eigenfunctions for the one-dimensional harmonic oscillator and Morse potentials and for ...

We propose and experimentally demonstrate a new chaos based opto-electronic secure communication system using voltage control oscillator. The chaotic signal has been generated using a modified electronic circuit of the logistic map. The output of the chaos generator is translated to a chaotically varying instantaneous frequency of the voltage controlled oscillator (VCO). The proposed technique ...

Electron transport through a quantum dot or single molecule coupled to a quantum oscillator is studied by the Keldysh nonequilibrium Green's function formalism to obtain insight into the quantum dynamics of the electronic and oscillator degrees of freedom. We tune the electronic level of the quantum dot by a gate voltage, where the leads are kept at zero temperature. Due to the nonequilibrium d...

An application Blocking Oscillator (BO) on a battery to power a system LED lamp light detector has been built and compared with a standard system used phone cellular adapter as the power supply. The performance analysis was carried out to determine the efficiency of the blocking oscillator and its potency to be adopted in an electronic appliance using low voltage and current from a battery. Mea...

The aim of this tutorial is to provide insight in the mechanism behind the behaviour of oscillators. A 10MHz negative resistance oscillator is used as an example. A hysteresis phenomena in connection with the negative resistance characteristic is found. By means of piece wise linear modeling and the ”frozen eigenvalues” approach sinusoidal oscillations are investigated.
