The Complete Response of Circuits with Two Energy Storage Elements
IN THIS CHAPTER
In this chapter, we consider second-order circuits. A second-order circuit is a circuit that is represented by a second-order differential equation. As a rule of thumb, the order of the differential equation that represents a circuit is equal to the number of capacitors in the circuit plus the number of inductors. For example, a second-order circuit might contain one capacitor and one inductor, or it might contain two capacitors and no inductors.
For example, a second-order circuit could be represented by the equation
where x(t) is the output ...
