The aim of this work is developing new noise-immune methods and devices for forming, processing and measuring wide-band signals with regular and chaotic dynamics for radio-informational systems of industrial and military objects. The subject of study is static and dynamic characteristics of devices for processing and measuring radio signals with frequency information encoding on a base of capacitance and inductance effects in semiconductor structures with negative resistance and quantum effects in Josephson junctions. In the research work available electric circuits of deterministic chaos oscillators have been improved, new circuits have constructed, and their theoretical basis has been developed. These oscillators operate using non-linear and reactive characteristics of the transistor structures with negative resistance. For deterministic chaos oscillators based on transistor structures with negative resistance the new mathematical models have been proposed and those available have been improved. Theoretical and experimental results and those of computer schematic simulation of the designed oscillators have been adduced. Time and frequency characteristics of deterministic chaos signals in additive white noise and noise-free environments have been investigated.
