Quasisinusoidal oscillators with cubic-type nonlinearity

It is shown how nonlinearities of cubic type, regardless of their degree of nonlinearity, are appropriate in the synthesis of quasinusoidal oscillators of any order. The existence of a suitable `small parameter¿ ¿ in the linear circuit of the oscillator and the design of its parameters by simple conditions ensure quasinusoidal oscillation. Application examples involving some typical circuits are then given.
