This book presents a rigorous method for designing analog electronic filters, specifically Butterworth filters, which are used to control how electrical signals pass through circuits. The author has developed a systematic algebraic approach that exploits the inherent symmetry of normalized Butterworth polynomials to formulate and solve algebraic equations directly for inductor and capacitor values at a specified cutoff frequency. Unlike traditional approaches that rely on approximations, lookup tables, or software...
