A massive challenge in network synthesis is that ideal brick-wall filters (which perfectly cut off unwanted frequencies) cannot be realized with a finite number of physical components. Van Valkenburg introduces approximation techniques to mimic these ideal responses using solvable polynomials:
One of the most practically useful concepts from Van Valkenburg is the , which is a systematic method to synthesize a driving-point impedance function ( Z(s) ) as a lossless two-port terminated in a resistor.

While the physical copies may yellow and the PDFs may be viewed on tablets rather than paper, the intellectual lineage of the book is unbroken. Every time an engineer places a pole in a stable region of the s-plane to create a filter, or checks a transfer function for realizability, they are walking the path that Van Valkenburg laid out. It remains an essential read for anyone seeking to master the art and science of circuit design.
M.E. Van Valkenburg's Introduction to Modern Network Synthesis is a foundational engineering text that reverses traditional circuit analysis by focusing on designing passive networks from desired performance characteristics. It covers essential topics including positive real functions, one-port Foster and Cauer forms, and two-port methods like Darlington and Guillemin. For more information, visit Internet Archive .

Rarely does an engineering requirement come in the form of a perfect rational mathematical function. Usually, requirements dictate a specific frequency response—such as a brick-wall low-pass filter. Van Valkenburg masterfully explains , which involves finding a mathematically realizable transfer function that closely mimics the ideal response. The text covers:
