Nonlinear Circuit Analysis via Perturbation Methods and Hardware Prototyping

Figure 2

Magnitude-frequency plots of the third harmonic. The “gain”, $G$ of the $g(z)$ function is varied from $10$ to $1000$. This causes the band-pass shape of the $z_1^3$-contributed harmonic to shift to the right, while that contributed by $x_1^3$ falls in magnitude.
