If you can’t find the PDF and need a more modern text with similar rigor, try Analog Filter Design by M. E. Van Valkenburg (his other book, 1982) or Filter Design Handbook by Williams and Taylor.

Filter design is not just synthesis — it starts with approximation : finding a transfer function that meets gain/phase specs. Chapter 7’s coverage of Butterworth, Chebyshev, and elliptic approximations is among the clearest ever written. Introduction To Modern Network Synthesis Van Valkenburg.pdf

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. If you can’t find the PDF and need
