If you are working through this book for a class, here is the typical workflow for a synthesis problem:
Most circuit analysis courses teach Analysis: Given a circuit (R, L, C components), find the output voltage or transfer function.
Synthesis is the reverse problem:
Given a desired frequency response (or transfer function), find the circuit (components and topology) that realizes it.
Van Valkenburg’s book teaches you how to take a mathematical equation (like a polynomials) and turn it into a physical network of inductors, capacitors, and resistors. Introduction To Modern Network Synthesis Van Valkenburg.pdf
Van Valkenburg introduces the Darlington Method: realizing a lossless two-port network terminated in a single resistor.

Important note: While the book’s copyright is held by John Wiley & Sons (and later editions up to the 1990s), many universities have digitized their copies for internal use. Always respect copyright — use PDFs only if your institution has an authorized digital license or if the book is in the public domain (not yet the case for Van Valkenburg’s major works).
