Simple single-parameter models are presented for the instantaneous characteristics of nonlinear electronic systems. The models can easily provide closed-form expressions, in terms of the ordinary Bessel functions, for the amplitudes of the output components of the nonlinear systems excited by multisinusoidal signals. Moreover, being a single-parameter model, the nonlinear electronic circuit can be easily characterized using a set of measured data for the variation of the relative output third-order intermodulation over an appropriate range of input tone amplitudes of a two-tone equal-amplitude input signal.
