Controlling the oscillator frequency synchronization by a low-frequency drive
Anastasiia Y. Nimets, Klaus Schuenemann, Dmytro M. Vavriv
The dynamics of an oscillator driven by both low- and high- frequency external signals is studied. It is shown that both two- and three-frequency resonances arise due to a nonlinea…
Digital receivers for low-frequency radio telescopes UTR-2, URAN, GURT
V. Zakharenko, A. Konovalenko, P. Zarka +49
This paper describes digital radio astronomical receivers used for decameter and meter wavelength observations. This paper describes digital radio astronomical receivers used for d…
Controlling the Characteristics of Nanomechanical Resonators
Anastasiia Y. Nimets, Klaus Schuenemann, Dmytro M. Vavriv
The dynamics of nanomechanical resonators driven by both low- and high-frequency signals is studied. Considering, as an example, resonators made of a doubly-clamped beam with magne…
A Simple Method for Generating Electromagnetic Oscillations
Vyacheslav Buts, Dmitriy Vavriv, Oleg Nechayev +1
We propose a novel approach to the generation of electromagnetic oscillations by means of a low-frequency pumping of two coupled linear oscillators. A theory of such generation mec…
