In the form of a set of expressions for defining oscillators - gains under amplification operation, the approximation functions of frequency relationships of reactive two-terminal networks impedances and reactive elements parameters that form the above two-terminal networks, parameters of a resistive four-terminal network and its two-terminal networks 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. The findings of mathematical modelling and circuit simulation for oscillators at hand show that the given and represented spectral characteristics coincide adequately.
