Digital oscillators are a useful electronic system that can be used for different applications. Usually the frequency and amplitude stability is important. There are oscillators with different type of output signal e.g. sinusoidal, square etc. Some of them needs floating point multiply or look-up table etc. In this paper the digital quadrature oscillator with triangular output signal and amplitude...
A novel chaotic oscillator with time delayed feedback is described in this paper. The oscillator is based on simple nonlinear circuit, gain stage and delay line. Chaotic systems are characterized by an extreme sensitivity to initial conditions. In this paper, instead of initial condition, the initial input wave (or voltage) is used. For chaotic system control also the gain of the amplifier is changed...
Multi-wing chaotic attractors are highly complex nonlinear dynamical systems. A new four-scroll chaotic attractor was found by energy feedback controlling method in this paper. Spectral analysis shows that the system in the four-wing chaotic mode has very broad frequency bandwidth, verifying its random nature, and indicating the prospect for engineering applications such as secure communications,...
Computation complexity of a broad variety of practical design problems is known to be strongly depending on an imagination about the particular real-world situation. The contribution is based on the fact that our knowledge of reality is always incomplete. The proposed approach is based on the idea that new knowledge can be gained by comparison using the requirement of consistency of different physical,...
In this paper, a one new approach for synthesizing nonlinear circuits is presented. The system consists of nonlinear electronic circuits and linear electric part for simulating and constructing of nonlinear dynamics. One advantage of our approach is that it can be directly synthesize by means of nonlinear circuits from ordinary differential equations. Presented circuit is able to generate the robust...
In this paper, a new approach for synthesizing nonlinear electric/electronic circuits is presented. The advantage of this approach is that is possible directly synthesize nonlinear circuits from some ordinary differential equations. Presented circuit is able to generate the chaotic attractors. This system can be used e.g. for secure communication, modulation etc. The financial application is also...
In this paper, we present a new method for synthesizing nonlinear circuits directly from some special set of ordinary differential equations, resulting from a state space energy conservation principle. Derived circuits are able to generate a broad class of conservative chaotic attractors. Such systems can be used e.g. for secure communication, modulation etc. The designed systems can directly be realized...
