Abstract:

The mathematical models are constructed for multi-frequency oscillators and frequency modulators with the increased quasi-linear region of the control characteristic in the form of a set of expressions for defining oscillators - gains under amplification operation, frequency relationships of imaginary components of signal source impedances under amplification and load operation which are optimal in accord with the criteria of providing a given number of frequencies of signals being generated and the linearization of frequency control characteristics and their representation conditions. The authors show that given and represented spectral characteristics of signals being generated in mathematical modeling using Mathcad and circuit simulation using Orcad for oscillators under study coincide adequately.
