NUMERICAL SOLUTION TO A CLASS OF INVERSE PROBLEMS
FOR PARABOLIC EQUATION

Abstract. The generating equation and equations for amplitude and phase fluctuations of the parametric tube oscillator with delayed feedback are analyzed in the paper. The steady-state oscillation modes and the influence of fluctuations in the natural frequency of the oscillator on the operation of the self-oscillator and parametric “pumping” in the presence of interference are investigated. The domains for the parameters of the original equation corresponding to unstable nodes, stable nodes, and focii are identified.

Keywords: vacuum tube oscillator, parametric “pump,” steady state mode.
