This function simulates the functioning of a Wien bridge oscillator through the numerical solving of its descriptive second order differential equation. The negative feedback loop includes a simple incandescent lamp model, whose resistance, sensitive to the heating coming from Joule effect, stabilizes the gain of the oscillator amplifier.
