#216 In this tutorial episode I look at how components can be modeled to have frequency dependent parameters. I first analyze the way in which the basic passive components – the resistor, capacitor and inductor can be modeled using G-sources with the Laplace function, and then I look at how the values can be made frequency dependent.
