چکیده
In this report the problem of forming chaotic signals with prescribed spectrum is discussed. An approach to construction of single-transistor chaotic oscillators with preassigned spectrum on the basis of “active component (transistor) – passive quadripole closed in feedback loop” structure is proposed. On example of capacitive three-point oscillator it is shown that in the oscillator with such structure it is possible to obtain chaotic spectrum which envelope is close to the shape of the amplitude-frequency response of feedback loop of the system. The possibility of construction of new transistor oscillators with preassigned spectrum is demonstrated on the example of model of chaotic oscillator with 2.5 degrees of freedom. Index terms – Dynamic chaos, chaotic oscillator, chaotic power spectrum formation.

Chaotic oscillators design with preassigned spectral characteristics
At present, active search for possible chaos applications goes. However to apply dynamical chaos, it is necessary to have signal sources generating chaotic signals. As is known, chaotic oscillators play the role of the sources. Now, there is a large variety of chaotic oscillators which differ from each other by both the structure and elements, and which have various characteristics. On the othe...

متن کاملSynchronization, non-linear dynamics and low-frequency fluctuations: analogy between spontaneous brain activity and networked single-transistor chaotic oscillators.
In this paper, the topographical relationship between functional connectivity (intended as inter-regional synchronization), spectral and non-linear dynamical properties across cortical areas of the healthy human brain is considered. Based upon functional MRI acquisitions of spontaneous activity during wakeful idleness, node degree maps are determined by thresholding the temporal correlation coe...
