16.11 NON-LINEAR ELEMENTS

---

If our models include a device that is non linear we will need to linearize the model before we can proceed.

A non-linear system can be approximated with a linear equation using the following method.

1. Pick an operating point or range for the component.

2. Find a constant value that relates a change in the input to a change in the output.

3. Develop a linear equation.

4. Use the linear equation in the analysis (Laplace or other)

Consider the example below,
