Before you build a filter, you must understand the complex frequency variable, $s$. Van Valkenburg treats the $s$-plane not just as a graph, but as a map of physical behavior. You will learn how poles and zeros dictate the stability and transient response of a network. This section is heavy on math but creates the foundation for everything that follows.
Before Van Valkenburg, circuit design was largely an analysis problem (Given a circuit, find the voltage/current). Van Valkenburg shifted the focus to synthesis (Given a desired performance, find the circuit). introduction to modern network synthesis van valkenburgpdf
